5 angle regular pentagon     ( n-2)(180) = sum of interior angles

                                                 3 * 180 = 540      so each of the five angles =   540 / 5 = 108 degrees = a

 

 

a + b are supplementary ( they add to 180)          108 + b  = 180           you can finish....right ?
