Can someone pls Help me with geometry
RUDIKE [14]

∠P = 6x + 6

∠Q = 2x + 11

∠R = 2x + 3

    ∠P   +    ∠Q     +     ∠R    = 180

(6x + 6) + (2x + 11) + (2x + 3) = 180

                              10x + 20 = 180

                                        10x = 160

                                           x = 16

∠Q = 2x + 11   = 2(16) + 11   = 32 + 11   = 43
