The surface area of the right triangular prism with legs of 5 centimeters and 12 centimeters, a hypotenuse of 13 centimeters, and a height of 2 centimeters is 108 square centimeters.

Surface area refers to the total area of the surface of a three-dimensional object. When it comes to a right triangular prism, the surface area includes the area of all six faces.

Let's call the height of the triangular prism "h" and label the legs of the triangle "a" and "b". Using these values, we can find the area of the base of the triangular prism. The area of a right triangle is equal to 1/2 times the product of the legs, so the area of the base is

=> (1/2) * a * b = (1/2) * 5 * 12 = 30 square centimeters.

Next, we need to find the surface area of each of the three lateral faces. Each of these faces is a rectangle, so we can find the area by multiplying the height of the prism by the length of one of the sides of the triangle base.

The length of one side of the triangle base is equal to the hypotenuse, which is 13 centimeters. So, the surface area of each of the three lateral faces is

=> h * 13 = 2 * 13 = 26 square centimeters.

Finally, we can find the total surface area by adding the surface area of the base and the surface area of the three lateral faces.

The surface area of the base is 30 square centimeters, and the surface area of each lateral face is 26 square centimeters, so the total surface area is

=> 30 + 3 * 26 = 30 + 78 = 108 square centimeters.

Given a parallelogram ABCD with points B and D, we draw two lines such that line BM intersects CD at point M and line DN intersects BC at point N, and BM = DN. The intersection of these lines is point I. Our goal is to prove that IA is a bisector of angle BID.

To prove this, we first note that since ABCD is a parallelogram, AB is parallel to CD and AD is parallel to BC. This means that ∠BAD and ∠CDA are congruent, and ∠BAC and ∠DCB are congruent.

Next, we consider triangle ABM. Since BM is perpendicular to AB, we have ∠BAM = 90°. By the same reasoning, we have ∠BID = 90°. This means that IA is perpendicular to both AB and BD.

Since IA is perpendicular to AB and BD, it follows that IA bisects ∠BAD and ∠BDC. Additionally, we know that AB = BD and ∠BAD = ∠BDC, so it follows that IA bisects ∠BID.

This completes the proof that IA is a bisector of ∠BID. The key idea here is that a line perpendicular to two parallel lines bisects the angles formed by the intersection of the two parallel lines with a third line.

In conclusion, given a parallelogram ABCD with points B and D, the intersection of lines BM and DN, point I, is the bisector of angle BID. This result can be used to prove various geometric theorems and helps to understand the properties of parallelograms and their related figures.

Answer:

To find the sum of two complex numbers on the complex plane, we can simply add their real and imaginary parts separately. The real part of a complex number is the x-coordinate on the complex plane, while the imaginary part is the y-coordinate.

In this case, the two complex numbers are (-4-4i) and (4+2i). To find their sum, we add their real and imaginary parts separately:

Real part: -4 + 4 = 0

Imaginary part: -4 + 2 = -2

So, the sum of (-4-4i) and (4+2i) is 0 - 2i, which can be represented as a point on the complex plane with x-coordinate 0 and y-coordinate -2.

Answer:

y=-2x+1

Explanation:

you can see that the x goes up by 1 every time. Y goes down by 2 every time, because 1-2=-1, -1-2=-3, etc. So the -2 goes in your m part of y=mx+b. Then you need to figure out what y is when x is 0, for your y-intercept, or your b part of y=mx+b. The picture makes it simpler, showing that when x is 0, y is 1. Therefore, 1 is your b part of y=mx+b. If you put it all together, it looks like this:

Y=-2x+1

Step-by-step explanation:

It looks Iike the equation is in slope intercept form

[tex]y = mx + b[/tex]

m is the slope

b is the y intercept

Finding B is easy, it's just where X = 0. On this table, Y is 1 when X is 0.

Finding the slope. We'll take two different (X,Y) coordinates. Let's do the first two rows (0,1) and (1,-1)

Next we apply the slope formula. That being

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

So plugging that in

[tex] = \frac{ - 1 - 1}{1 - 0} [/tex]

To find the missing side lengths in the given right triangles, use trigonometric ratios.

[tex]\boxed{\begin{minipage}{9.4 cm}\underline{Trigonometric ratios} \\\\$\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf A$ is the side adjacent the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}[/tex]

From inspection of the first triangle ABC, we have been given the angle, the side opposite the angle and the side adjacent the angle.

Therefore, to calculate the length of the adjacent side, x, substitute the values into the tangent ratio:

[tex]\implies \tan 18^{\circ}=\dfrac{15}{x}[/tex]

[tex]\implies x\tan 18^{\circ}=15[/tex]

[tex]\implies x=\dfrac{15}{\tan 18^{\circ}}[/tex]

Triangle LMN is a right triangle. Interior angles of a triangle sum to 180°.

Therefore, as m∠M = 50° and m∠MLN = 90°, then m∠MNL = 40°.

As KN is perpendicular to NM and m∠MNL = 40° then m∠KNL = 50°.

As KL is parallel to NM, then m∠K = 90°.  Therefore, m∠KLN = 40°.

(Refer to the attached diagram).

For right triangle LMN, we have been given the angle (∠M) and the side adjacent to the angle (LM). To find an expression for the length of the side opposite the angle (LN), use the tangent ratio:

[tex]\implies \tan 50^{\circ}=\dfrac{LN}{45}[/tex]

[tex]\implies LN=45\tan 50^{\circ}[/tex]

LN is the hypotenuse of right triangle KLN.

If we use ∠KNL as θ, then side KN is adjacent to the angle.

Therefore, to find the KN use the cosine ratio:

[tex]\implies \cos 50^{\circ}=\dfrac{KN}{LN}[/tex]

[tex]\implies \cos 50^{\circ}=\dfrac{KN}{45\tan 50^{\circ}}[/tex]

[tex]\implies KN=45\tan 50^{\circ}\cos 50^{\circ}[/tex]

[tex]\implies KN=34.471999...[/tex]

[tex]\implies KN=34.5\;\; \sf (nearest\;tenth)[/tex]

As KL is the side opposite ∠KNL, to find KL use the sine ratio:

[tex]\implies \sin 50^{\circ}=\dfrac{KL}{LN}[/tex]

[tex]\implies \sin50^{\circ}=\dfrac{KL}{45\tan 50^{\circ}}[/tex]

[tex]\implies KL=45\tan 50^{\circ}\sin50^{\circ}[/tex]

Step-by-step explanation:

First we divide the final number of cakes by the initial

[tex]72 \div 18 = 4[/tex]

Then we multiply each of the ingredients by 4

[tex]150 \times 4 = 600[/tex]

[tex]500 \times 4 = 2000[/tex]

[tex]50 \times 4 = 200[/tex]

A ratio has two or more numbers that symbolize relation to each other. Ratios are used to compare numbers, and you can compare them using division.

The ratio for this problem is:

(Ingredients: number of cakes)

Therefore, we need to know how many times 18 can fit into 72.

Now, if we know that 18 can be multiplied by 4 to get 72, we need to multiply all of the ingredients by 4.

Therefore, if the recipe stays proportional, we will need 600g butter, 200g flour and 200g sugar to make 72 cakes.

The 8 painters will take 12 hours and 9.6 minutes to paint the office. The result is obtained by comparing the two variables, worker and time duration.

If the they work at the same rate, find the time needed for the 8 painters to finish their job!

Let's say

We convert the unit of time in hours.

t₁ = 7 h 36 min

t₁ = (7 + 36/60) h

t₁ = (7 + 0.6) h

t₁ = 7.6 hours

If they work at the same rate, the number of workers and time durations of each day are directly proportional. So,

w₁/w₂ = t₁/t₂

5/8 = 7.6/t₂

t₂ = 8/5 × 7.6

t₂ = 12.16 hours

In hours and minutes,

t₂ = 12 h + (0.16 × 60) min

By applying the algebra concept, it can be concluded that p = 3x or p = 2 - 3x.

Algebra is a branch of mathematics that uses symbols and mathematical operations, such as addition, subtraction, multiplication, and division to solve problems.

We want to express p in terms of x of this equation:

9x² – 6x + 5 = p² – 2p + 5

First, we have to eliminate 5, so we have:

Then we add 1 on each side, so we have:

9x² – 6x + 1 = p² – 2p + 1

       (3x - 1)² = (p - 1)²

            p - 1 = √(3x - 1)²
