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

Question

campbell_st · Answer

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
