I need help fast.
If each interior angle of a regular convex polygon is three times the measure of each exterior angle, what kind of polygon is it?

A baseball diamond’s home plate has three right angles. The remaining two angles are congruent. What are their measures?

Answer 1

Since the interior and exterior angles add up to 180 degrees, the exterior angle is therefore 1/4 of 180=45 degrees.
The sum of all exterior angles of a regular polygon is 360 degrees, so the number of sides can be obtained by division of 360 by 45.
