Area of triangle = 1/2 x base x height

Area of the triangle = 1/2 x 22 x 18 = 198 square m.

Area of semi circle = 1/2 x PI x r^2

Area of semi circle = 1/2 x 3.14 x 11^2 = 189.97 square m.

Total area = 198 + 189.97 = 387.97 square m.

Round up to 388 square m.

The length of a rectangle is 5 more than twice the width. If the perimeter of the rectangle is 34 cm find the length?

In this question we are provided with the perimeter of the rectangle = 34 cm and it is given that the length of the rectangle is 5 more than the twice it's breadth and asked to find out the length of the rectangle.

[tex] \small \orange{ \underline{\rm \blue{length \: of \: a \: rectangle \: is \: 5 \: more \: than \: twice \: the \: width.}}}[/tex]

Let us assume breadth as x then length = 2x +5

We know,

[tex] \star \: \large\boxed{ \rm{ Perimeter_{(rectangle)} = 2(length + breadth)}}[/tex]

Substituting the values we get

34 = 2(2x +5 + x)

→ 34 = 2(3x + 5)

→ 34 = 6x + 10

→ 34 - 10 = 6x

→ 24 = 6x

→ [tex]\dfrac{24}{6}[/tex] = x

x = 4

Length = 2x + 5 = 2 × 4 + 5 = 8 + 5 = 13 cm

Breadth = x = 4cm

Length = 13 cm.

Answer:

d multiplication ‌ ‌ ‌ ‌ ‌

Answer:

Okay, here's the method I'm going to use.

If you drive north 6 miles, and then drive east 19 miles, you are technically making a triangle.

You are just missing the last side of the triangle: the straight line stretching from across your starting point to the ending point. You can find this by using the Pythagorean theorem.

a^2 + b^2 = c^2

6^2 + 19^2 = c^2

36 + 361 = c

397 = c

Answer:

17=x

Step-by-step explanation:

In this case, we need to use Vertical Angles Theorem to solve this problem. Basically, because of the position of the angles, they are congruent.

68-x = 3x

Add x to both sides

68=4x

Divide by 4

17=x

Hope this helps!

Answer:

The value of 'x' is: 17°

Step-by-step explanation:

From what is being shown, there are two angles that are given:

(68 - x)°

3x°

Since they are congruent angles, meaning they are equal to each other, they will be put into a(n) equation such like shown below:

(68 - x)° = 3x°

(Then remove the parenthesis)

68° - x° = 3x°

     + x°=+3x°

------------------

68° = 4x°

------------------

(Divide both sides by 4)

[tex]\frac{68}{4} = \frac{4x}{4}[/tex]

------------------

17° = x

------------------

Your value of 'x' is 17.

Answer: x= 4/3 but in decimal form =1.333

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    4-(2*(3*x-2))=0

4 -  2 • (3x - 2)  = 0

Pull out like factors :

  8 - 6x  =   -2 • (3x - 4)  

Solve  :    3x-4 = 0  

Add  4  to both sides of the equation :  

                     3x = 4

Divide both sides of the equation by 3:

                    x = 4/3 = 1.333

Answer:

x= undefined

Step-by-step explanation:

In order to make u understand , if u multiply 2(3x-2) it becomes 6x-4 which is the exact same as the left hand side . Therefore u cant find x from here in this manner .

For this however we can try the method bellow .

Lets say f(x)=y=6x-4=2(3x-2)

we can get the followig points for inserting domains and finind the domains . we can make graph for each . (We will not do them however)

As we have seen that both of those parts of the equation are one and the same so they will produce the exact same Line or curve .

Therefore every signle points on them r the same exact points and there fore they are the same exact line .

So the value of x is undefined and can be anything between every points on that line (Which can be infinit amounts of points) .

Answer:

The rate of change is 0.75 gallons per minute

Step-by-step explanation:

The rate of change of the linear relation is represented by the slope of the line which represents this relation

The rule of the slope of a line is

m = Δy/Δx, where

From the given graph

∵ The line passes through points (0, 0) and (4, 3)

∴ Δx = 4 - 0 = 4

∴ Δy = 3 - 0 = 3

→ Use the rule of the slope above to find the slope of the line

∴ m = [tex]\frac{3}{4}[/tex] = 0.75

∵ The x-axis represents the time in minutes

∵ The y-axis represents the amount in gallons

∵ m represents the rate of change

∴ The rate of change = 0.75 gallons per minute

Step-by-step explanation:

Open the brackets on both sides

12r + 16 = -16r - 40

collect like terms

12r + 16r = -40 - 16

28r = -56

r = -56/28

r = -2

So first we have to find equation form angles.

Statement :- The measure of the second angle of a triangle is 20 more than the measure of the first.

Equation :-

second angle = 20 + x

{ Remember people get's confused when to multiply and when to add. when ever there "more than" then we will add and when there is ,"times" we will multiply}

Statement :-

the third angle is 10 less than three times the first

Now just see first less means we have to subtract 10 from 3 times the first means 3 × first angle.

Equation :-

third angle = 3x - 10

Now let's represent :-

We know sum of angles of triangle is equal to 180°

Let the first angle be x

According to the question,

[ 2nd angle is 20 more than the first angle ]

[ 3rd angle is 10 less than thrice times the first angle ]

By using Angle sum property

That is,

[tex]\sf{ x + ( x + 20) + ( 3x - 10) = 180{\degree}}[/tex]

[tex]\sf{ x + x + 20 + 3x - 10 = 180{\degree}}[/tex]

[tex]\sf{ 5x + 10 = 180{\degree}}[/tex]

[tex]\sf{ 5x = 180 - 10}[/tex]

[tex]\sf{ 5x = 170}[/tex]

[tex]\sf{ x = }{\sf{\dfrac{ 170}{5}}}[/tex]

[tex]\sf{ x = }{\sf{\cancel{\dfrac{ 170}{5}}}}[/tex]

[tex]\bold{ x = 34{\degree}}[/tex]

Thus,

Hence, The three angles of the given triangle are 34° , 54° and 92°

Answer:

x = 33°

explanation:

The interior angles sum up to 180°

solve:

x + 20° + 4x - 5° = 180°

x + 4x + 20° - 5° = 180°

5x + 15° = 180°

5x = 180° - 15°

5x = 165°

x = 33°

Answer:

x = 33

Step-by-step explanation:

Sum of consecutive interior angles = 180°

⇒ (x + 20) + (4x - 5) = 180

⇒ 5x + 15 = 180

⇒ 5x = 165

⇒ x = 33

Answer:

m∠JTS = 104° ⇒ (A)

Step-by-step explanation:

The measure of an exterior angle of a triangle at one of its vertices equals the sum of the measures of the opposite interior angles.

Let us use this fact to solve the question

In ΔTSR

∵ T ∈ ray RJ

∴ ∠JTS is an exterior angle of ΔTSR

→ By using the fact above

∴ ∠TSR and ∠TRS are the opposite interior angles to ∠JTS

∴ m∠JTS = m∠TSR + m∠TRS

∵ m∠JTS = 27x - 4

∵ m∠ TSR = 30°

∵ m∠TRS = 18x + 2

→ Substitute their values in the equation above

∴ 27x - 4 = 30 + 18x + 2

→ Add the like terms in the right side

∴ 27x - 4 = 18x + 32

→ Add 4 to both sides

∴ 27x = 18x + 36

→ Subtract 18x from both sides

∴ 9x = 36

→ Divide both sides by 9

∴ x = 4

→ To find m∠JTS substitute x by 4 in its measure

∴ m∠JTS = 27(4) - 4 = 108 - 4

∴ m∠JTS = 104°
