Answer:

9x-2

The measure of<br> an exterior angle<br> of a regular<br> octagon is x + 10.<br> Find x.
elena-s [515]

Answer:

x = 35

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Then

1 exterior angle = 360° ÷ 8 = 45° , so

x + 10 = 45 ( subtract 10 from both sides )

x = 35
