Question

Approximately how many degrees are in the measure of an interior angle of a regular seven sided polygon?

A. 102.9
B. 128.6
C. 180.0
D. 231.4

Answer 1

The correct answer is B: 128.6 degrees

Answer 2

The interior angle of a regular polygon is equal to each other since all sides of the polygon are congruent. In this case, the formula that expresses the relation of the sides of the polygon and the measurement of interior angle is (n-2)*180/n where n is 7. Each interior angle then measures B. 128.6 degrees
