Answer:

  ∠S = 38°

Step-by-step explanation:

The sum of angles in a triangle is 180°, so you have ...

  (x+17)° +(2x-2)° +(5x+5)° = 180°

  8x +20 = 180  . . . . .  divide by °, collect terms

  8x = 160 . . . . subtract 20

  x = 20 . . . . . . divide by 8

∠S = (2x -2)° = (2·20 -2)°

∠S = 38°
