Question

solve this question step wise

Answer 1

angle APR = angle PRD ( alternate interior )

angle APR = 110

angle PQR = 110 - 55 ( alternate interior )

                   = 55

angle PRQ =  180 - 110 ( linear pair )

                      = 70

angle QPR = 110 - 55

                  = 55

angle RPB = 180 - (55 + 55) ( linear pair)

                 = 180 - 110

                  = 70

hence, angle PQR = 55, PRQ = 70 , QPR = 55 , PRB = 70
