Answer 3

The sum of measures of the interior angles in any figure is \(180(n- 2)\)
hmmm
n = number of sides

Answer 4

just find the exterior angle.. do you know how to?

Answer 5

First find the interior angle.

\( \color{Black}{\Rightarrow \Large {180(n- 2) \over n}}\)

Then find the exterior angle, then sum em up.
