Step-by-step explanation:

Given : 3 angles of a Δ

  • (x + 5)°
  • (x + 10)°
  • (x + 15)°

Solving :

  • According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°
  • x + 5 + x + 10 + x + 15 = 180
  • 3x + 30 = 180
  • x + 10 = 60
  • x = 50

Finding the angles

  • x + 5 = 50 + 5 = 55°
  • x + 10 = 50 + 10 = 60°
  • x + 15 = 50 + 15 = 65°
