A regular pentagon and a regular hexagon are coplanar and share a common side \(\overline{AD}\), as shown. What is the degree measure of angle \(BAC\)?
(6-2)(180)/ 6 = (3/4) 180 = 135 = BAD Agreed; it's BAD!
----------------------------------------------------------------
Angle BAC = 120 - 108 = 12º
Interior angle of tegular hexagon = (6-2)(180)/ 6 = (2/3) 180 = 120 = BAD
Interior aangle of regular pentagon = (5-2) (180)/5 = 108 = CAD
BAC = BAD - CAD = 120 - 108 = 12°
Corrected !!!
