Using the fact that ∠13 and ∠14 are supplementary angles, we will get:

  • x = 24
  • m∠13  = 107°
  • m∠14  = 73°

How to find the value of x?

Notice that the angles ∠13 and ∠14 are supplementary angles, which means that the measures add up to 180°.

  • The measure of angle ∠13 is: 4x + 11
  • The measure of angle ∠14 is: 3x + 1

Then we should have that:

(4x + 11) + (3x + 1) = 180

Now we need to solve that linear equation for x, we will get:

(4 + 3)*x + (11 + 1) = 180

7x + 12 = 180

7x = 180 - 12 = 168

x = 168/7 = 24

The value of x is 24, and the measures of the angles are:

  • The measure of angle ∠13 is: 4x + 11
  • The measure of angle ∠14 is: 3x + 1

  • m∠13 = 4*24 + 11 = 107°
  • m∠14 = 3*24 + 1 = 73°
