  • All angles in a triangle add up to 180°

Step-by-step explanation:

Step 1: Set Up Equation

69° + 62° + (x + 54)° = 180°

Step 2: Solve for x

  1. Combine like terms:                    x + 185 = 180
  2. Subtract 185 on both sides:        x = -5

Answer:

Step-by-step explanation:

x + 54 + 69 + 62 = 180         Every triangle has 180 degrees

x + 185 = 180                        Subtract 185 from both sides

x = - 5
