1. Vertex angle = (n - 2)(180)
= (8 - 2)(180)
= 6 x 180
Vertex angle = 1,080°
2. Vertex angle = (n - 2)(180)
= (6 - 2)(180)
= 4 x 180
Vertex angle = 720°
3. Vertex angle = (n - 2)(180)
= (7 - 2)(180)
= 5 x 180
Vertex angle = 900°
4. 1,260 = (n - 2)(180)
1,260/180 = [(n - 2)(180)]/180
n - 2 = 7
n = 7 + 2
n = 9
The number of sides of the polygon is 9
5. 1,980 = (n - 2)(180)
1,980/180 = [(n - 2)(180)]/180
n - 2 = 11
n = 11 + 2
n = 13
The number of sides of the polygon is 13
