PLEASE FAST 20 POINTS
An octagon has 8 sides. One angle of a regular octagon measures (9w + 8)°. Determine the value of w. Round to the nearest whole number.

w = 19
w = 16
w = 14
w = 135

Answer 1

For the octagon whose measure of angle is (9w + 8)°, the value of w is 14.

What is angle?

An angle is the formed when two straight lines meet at one point, it is denoted by θ.

Given that,

Angle of regular octagon = 9w + 8

Since, angle of an octagon is 135°

Equate 9w + 8 to 135,

9w + 8 = 135

9w = 127

w = 14.11

w = 14

The required value of w is 14.
