# Chapter 6 - Polygons and Quadrilaterals - 6-1 The Polygon Angle-Sum Theorems - Practice and Problem-Solving Exercises - Page 356: 12

135 degrees

#### Work Step by Step

First, we use the formula to find the total degrees in a given polygon: $(n-2)180$ Where n represents the number of sides. We then substitute $n$ for 8, $(8-2)180$. This gives us 1080. Finally, we divide by 8, since the polygon in question has 8 angles. $1080\div8=135$
