Question

The measures of the exterior angles of an octagon are x°, 2x", 3x°, 4x °, 6x°, 7xº,

8xº, and 9x °. Find the measure of the largest exterior angle.

Answer 1

216

Explanation:

Total of octagon amount is 1080, so set it equal.

x + 2x + 3x + 4x + 6x + 7x + 8x + 9x = 1080

45x = 1080

/45 /45

x = 24

Then plug in for largest number.

9 (24) = 216
