Answer:

1. x = 16

2. x = 17

Step-by-step explanation:

1. The sum of the exterior angles of any polygon is 360 degrees. So, to find x, we can add up all of the angle measures and set them equal to 360, then solve for x:

46 + 93 + 47 + 4x + 62 + 3x = 360

Combine like terms:

248 + 7x = 360

Subtract 248 from both sides of the equation to isolate 7x:

7x = 112

Divide both sides by 7 to find the value of x:

x = 16

2. The sum of the interior angles for a 5-sided polygon is 540 degrees. So, to find x, we can add up all of the angle measures and set them equal to 540, and then solve for x:

5x + 139 + 9x + 71 + 92 = 540

Combine like terms:

14x + 302 = 540

Subtract 302 from both sides to isolate the 14x:

14x = 238

Divide both sides by 14 to find the value of x:

x = 17

I hope this helps :)

Question 2

mylen [45]

Answer:

Part A: OC. 16π square inches

Part B: OC. 36π square inches

Step-by-step explanation:

Part A:

Given

Diameter of circular picture = d = 8 inches

We need to find the radius first to find the area

So,

Rdius = r = d/2 = 8/2 = 4 inches

$Area = \pi r^2\\= \pi *(4)^2\\= 16\pi\ square\ inches$

Therefore, option C is the correct answer..

Part B:

As two inches frame is added around the picture, the diameter will become 8+4 =12 inches

The new radius will be:

r = 12/2 = 6

So,

$Area\ with\ frame = \pi r^2\\=\pi *(6)^2\\=36\pi\ square inches$

Therefore, option C is correct ..

Need help with the question at the top Thanks

Effectus [21]

First we must find area of a single square.

Meaning we divide total area of 80 centimetres squared by 5 since we have 5 squares in the shape.

$A_{square}=\frac{A_{shape}}{5}=\underline{16}$

Now from the picture we can see that the perimeter of shape is combined by 4 times 3 times the length of side of 1 square.

So we need to find side of 1 square.

$a=\sqrt{A_{square}}=\sqrt{16}=\underline{4}$

As we stated before the formula for perimeter of this shape is:

$P=4(3\cdot a)=4(3\cdot4)=4\cdot12=\boxed{48}$

The perimeter of shape is 48 centimetres.

Hope this helps.
