Question

The measures of all angles in a regular octagon are (4x + 12)°. Find the value of x. Show equations and all work that leads to your answer

Answer 1

well the angle sum of a polygon is

Angle Sum = 180(n -2)

where n = the number of sides in the polygon

A regular polygon has all sides and angles equal in their measurements.

so to find the value of x you need

\[4x + 12 = \frac{anglesum}{8}\]

hope it helps
