Answer:

  • x = 5; 85°; 52°; 43°

Explanation:

Sum of interior angles of a triangle is 180

  • m∠A + m∠B + m∠C = 180°
  • 17x + 12x - 8 + 8x + 3 = 180
  • 37x - 5 = 180
  • 37x = 185
  • x = 185/37
  • x = 5

Find each angle measure

  • m∠A = 17*5 = 85°
  • m∠B = 12*5 - 8 = 52°
  • m∠C = 8*5 + 3 = 43°
