If this is a 100-gon, then not only does it have 100 sides, it also has 100 central angles. Each one measures 360/100 = 3.6. This is the vertex angle for each of those 100 triangles. 180 - 3.6 = 176.4, which has to be split equally between the 2 base angles. This puts each of those at 88.2. If you are looking for the exterior angle to each of those, it's the supplement of them. 180-88.2 = 91.8
Answer:
Step-by-step explanation:
To find the area, I divided the shape into squares and rectangles. Then, I found the area of the squares and rectangles and added them,
- Area = (7 x 7) + (18 x 5) + (6 x 4)
- => (49) + (90) + (24)
- => 163 in²
Hence, the area is 163 in.²
2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n -2
6n - 2 = 6n - 2 (equal)
6n - 6n = 2 - 2
0 = 0
whatever value you put into the place of n, you'll get 0 = 0
