Question

Can any math genius help me with this

Answer 1

Here's my working for 1) You need to find the exterior angle, then divide by 360 to find the number of sides:

Applying these steps :

180 (Interior Angles) - 162 = 18 (Exterior angle)

360 ÷ 18 is 20 sides

For 2)

Its the same method, so apply the steps:

180 - 175 = 5

360 ÷ 5 = 72 sides

Hope it helps! :)
