Answer:

x = 7°

Explanation:

Using the exterior angle theorem (the sum of the two opposite angles in the triangle equals the exterior angle)

Solve:

  • (3x + 17) + (3x + 11) = 11x - 7
  • 6x + 28 = 11x - 7
  • 28 = 5x - 7
  • 35 = 5x
  • x = 7

The value of x = 7

There is a picture attached for this problem.
