The ratio between the exterior and interior angle of a regular polygon is 1:5, find a. the measure of each exterior angle.
b. the measure of each interior angle.
c. the number of sides of the polygon.

Exterior and interior angles are supplementary, meaning they sum to 180 degrees. If the exterior and interior angles are x and 5x respectively, we can write x + 5x = 180, and solving for x we get x = 30°. This means that the answer to a) is 30° and the answer to b) is 30 * 5 = 150°.

For c), to find the number of sides we can do:

180 - 150 = 30

180 / 30 = 6 so the answer to c) is 6.
