What is Triangle?A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.
What is the condition to be congruent?If two triangles are the same size and shape, they are said to be congruent. To establish that two triangles are congruent, not all six matching elements of either triangle must be located. There are five requirements for two triangles to be congruent, according to studies and trials. The congruence properties are SSS, SAS, ASA, AAS, and RHS.

Please solve
-5|x+3|-3=-15
I got the x + 3 =12/5 part but I don’t know what to do after that
please help me including the steps to get the next part.
Thank you!
To solve the equation, you can use the following steps:
Start by isolating the absolute value expression on one side of the equation:
-5|x+3| = 18
Now, since the absolute value is positive, it has two solutions:
x + 3 = -18 or x + 3 = 18
Solving for x in each case:
x = -21 (if x + 3 = -18) or x = 15 (if x + 3 = 18)
So the two solutions to the equation are x = -21 and x = 15.

12. The circle graph represents the jobs at a digital
animation company with 1540 employees
How many more story artists are there
than interns?
Answer:
231
Step-by-step explanation:
From the pie chart we see that the story artists constitute 20% of the total employee strength of 1540 employees and the interns constitute only 5% of that number
In actual values
Number of story artists = 1540 x 20% = 1540 x 20/100 = 308
Number of interns = 1540 x 5% = 1540 x 5/100 = 77
Difference = 308 - 77 = 231

-The diagram shows a triangular prism.
-The base, ABCD, of the prism is a square side 14cm.
-Angles ABE and CBE are right angles.
-Angle EAB =32 degrees
-M is the point on DA such that DM : MA = 3:4
-Calculate the size of the angle between EM and the base of the prism.
-Give your answer to 1 decimal place.
The size of the angle between EM and the base of the prism is equal to 28.5°.
How to calculate the size of the angle between EM and the base of the prism?First of all, we would determine side length MA based on the ratio between side lengths DM and MA as follows;
DM : MA = 3 : 4
Total side parts = 14 cm
(3 + 4) parts = 14 cm
7 parts = 14 cm
1 part = 2 cm
Therefore, side length MA = 2 × 4 = 8 cm.
By applying Pythagorean's theorem to right triangle MAB, we have the following:
c² = a² + b²
Where:
a, b, and c represents the side lengths of a right triangle.
c² = 8² + 14²
c² = 260
c = √260
c = 16.1245 cm.
By applying tan trigonometry to right triangle AEB, we have:
tanθ = opposite/adjacent
opposite = tan32° × 14
opposite = 8.7482 cm.
By applying tan trigonometry to right triangle EMB, we have:
tanθ = opposite/adjacent
θ = tan⁻¹(opposite/adjacent)
θ = tan⁻¹(8.7482/16.1245)
θ = tan⁻¹(0.5425)
θ = 28.5°.

Step-by-step explanation:
Because MN connects the midpoints M and N of AD and BC respectively
MN is the midsegment of trapezoid ABCD , then
MN = [tex]\frac{AB+DC}{2}[/tex]
AB + DC = 6x + 7 + 8x - 1 = 14x + 6
MN = [tex]\frac{14x+6}{2}[/tex] = [tex]\frac{14x}{2}[/tex] + [tex]\frac{6}{2}[/tex] = 7x + 3
Given the function of f(x)
To evaluate [tex]f(g(3))[/tex], we need to first evaluate g(3), then evaluate f(g(3)).
[tex]$$g(3)=7 \cdot 3^2+6 \cdot 3+2=65$$[/tex]
How to solve the given equation?A relationship between a number of inputs, each of which has an output, is known as a function. A function is, to put it simply, a relationship between inputs that are individually connected to exactly one output. There are two domains or scopes for each function. f is typically used to represent functions (x). The input is x. Y = f is a common way to represent the function (x).
To evaluate [tex]f(g(3))[/tex], we need to first evaluate g(3), then evaluate f(g(3)).
[tex]$$g(3)=7 \cdot 3^2+6 \cdot 3+2=65$$[/tex]
So
[tex]f(g(3))=f(65)=\frac{1}{2} \cdot 65-4=\frac{1}{2} \cdot 65-4=28[/tex]
To evaluate [tex]g(f(8))[/tex], we need to first evaluate [tex]f(8)[/tex], then evaluate [tex]f(8)[/tex].
[tex]f(8)=\frac{1}{2} \cdot 8-4=2\\\\g(f(8))=g(2)=7 \cdot 2^2+6 \cdot 2+2=46\\g(f(8))=46[/tex]
[tex]g\left(\frac{1}{8}\right)=7\left(\frac{1}{8}\right)^2+6 \cdot \frac{1}{8}+2=\frac{121}{8}+\frac{3}{2}+2=\frac{135}{8}[/tex]
[tex]f\left(g\left(\frac{1}{8}\right)\right)=f\left(\frac{135}{8}\right)=\frac{1}{2} \cdot \frac{135}{8}-4=\frac{135}{16}-4=\frac{135-64}{16}=\frac{71}{16}\\f\left(\frac{1}{2}\right)=\frac{1}{2} \cdot \frac{1}{2}-4=-4[/tex]

Write down the complex number that has a real part 0 and an imaginary part ✓11
Answer:
0 + 11i
Step-by-step explanation:
A complex number is a number in the form a + bi, where a is the real part and b is the imaginary part. In this case, the real part is given as 0 and the imaginary part is given as 11. Therefore, the complex number is:
0 + 11i
where 0 is the real part and 11i is the imaginary part.

By the given explanation,
It is proven that in given right angle triangles a² = cx.
Congruent angles:The angles that are identical to each other are known as Congruent angles. The measure of these concurrent angles is always equal to each other.
They can be acute, obtuse, exterior, or interior angles because the congruence of angles is unaffected by the type of angle. As we know a right angle is 90° all right angles are congruent angles.
Here we have
Two right-angle triangles MOP and MNO
Measurements of Δ MNO side are a, b, and c is the hypotenuse
Measurements of Δ MOP sides are a, x, and OP is the hypotenuse
Here we need to prove that a² = c x
We can prove its as follows
As we know all right angles are concurrent
Statement Reason
=> ∠NOM ≅ ∠OPM [ ∵ right-angles are concurrent ]
=> ∠OMN≅ ∠PMO [ ∵ Common angle ]
=> ΔMOP ~ ΔMNO [ By Angle - Angle - Angle criteria ]
Since ΔMOP ~ ΔMNO
=> a/x = c/a [ ratio of the corresponding side ]
=> a² = cx [ Corss multiplication ]
Therefore,
It is proven that in give right angle triangles a² = cx.

what is percentage ?In arithmetic, a percentile is a number or statistic that is given as a fraction of 100. Occasionally, the acronyms "pct.," "pct," nor "pc" are also used. But it is broadly classified into the following by the cent sign, "%." The % amount has no characteristics. Percentages are essentially integers when the denominator is 100. Use the percent sign (%) to indicate that a number is a percentage by placing it close to it. For instance, you score a 75% if you properly answer 75 so out 25 pages on a test (75/100). Divide the money by the whole and multiply the results by 100 you compute percentages. The formula for calculating the percentage is (value/total) x 100%.
