What is the sum of the interior angle of a 30 sided polygon?
Sum_of_interior_angles = (number_of_sides - 2) × 180° → for a 30-gon sum = (30 - 2) × 180° = 5040°
What is the measure of an angle complementary to an angle that measures 150?
Two angles are complementary if their sum equals exactly 90 degrees. Two angles are supplementary if their sum equals exactly 180 degrees, so a 30 degree angle is supplementary with a 150 degree angle.
If a regular polygon has exterior angles that measure 30 each how many sides does the polygon have?
We know that the sum of a polygon's exterior angles, one at each vertex, equals 360 degrees. So at each angle extended from each side there is an angle of 30 degrees. If x= number of sides, then 30x = 360. Divide by 30 and x = 12.
