8 sides
the exterior angle = 180° - 135° = 45° ( exterior/ interior are supplementary )
the sum of the exterior angles of a polygon = 360°
number of sides = 
= 8
Answer:
Step-by-step Explanation:
Given:
∆UVW,
m < U = 33°
m < V = 113°
VW = u = 29 m
Required:
Area of ∆UVW
Solution:
Find side length UV using Law of Sines
U = 33°
u = VW = 29 m
W = 180 - (33+113) = 34°
w = UV = ?
Cross multiply
Divide both sides by sin(33) to make w the subject of formula
(rounded to nearest whole number)
Find the area of ∆UVW using the formula,
(to nearest tenth).
9 to the 3 half power is 27. Hope that's what your wanting to know.

Hey,
So we have to solve this in multiple steps. Step 1 is to find the circumference of the semi-circle and multiply by three since there are three. Step 2 would be to find the perimeter of the rectangle. Step 3 would be to add those two together.
Step 1: To find the circumference of the semicircle use the formula pi (3.14) times radius (8 ÷ 2 = 4) times 2. After that we will divide by two since there is only half. After that we will multiply that answer by three.
C = 3.14 x 4 x 2
C = 12.56 x 2
C = 25.12
C = 25.12 ÷ 2
C = 12.56
Perimeter = 12.56 x 3 = 37.68
Step 2: To find the perimeter of the rectangle/square add all the sides (8).
Perimeter = 8 + 8 + 8 + 8 = 32
Step 3: Now add the two previous answers to get the final perimeter.
37.68 + 32 = 69.68
Final Answer: 69.68
Hope this helped!
Cheers,
Izzy
