Question

A regular pentagon, a regular octagon, and∠ meet at a point. What is m< SBY?

Answer 1

Answer:

117

Step-by-step explanation:

Each angle of a regular pentagon = 108

Each angle of regular octagon = 135

135+ 108 + ∠SBY = 360

       243 + ∠SBY = 360

                 ∠SBY = 360 - 243

∠SBY = 117°
