Question

The measures of the exterior angles of a heptagon are x, 4x, 5x, 6x, 7,x 8x, and 9x. Find the measure of the smallest exterior angle.

Answer 1

9°

Explanation:

x + 4x + 5x + 6x + 7x + 8x + 9x = 360

40x = 360

x = 9

The smallest angle measures x, and x = 9, so its measure is 9°.

Answer: 9°
