Question

Can you guys help me how to solve these problems step by step? Plzz

Answer 1

8-the formula to find an exterior angle of a polygon is:
360/n
(n is the number of sides of the polygon)

so the answer is 40

`(360)/(9) = 40`




9 - the formula to find an interior angle of polygon is:

`((n - 2) * 180)/(n)`
so the answer is 135

`((8 - 2) * 180)/(8) = (6 * 180)/(8) = (1080)/(8) = 135`




good luck
