Answer:

40

Step-by-step explanation:

Sum of all angles of triangle = 180°

∠W + ∠X + ∠Y = 180

10x + 17 + 2x - 9 + 3x + 7 = 180

10x + 2x  +3x + 17 - 9 + 7 = 180

Combine like terms

15x + 15 = 180

       15x = 180- 15

         15x = 165

            x = 165/15

x = 11

∠Y =  3x +7  = 3*11 + 7 = 33 + 7 = 40
