Angles

Find the value of x.

Shown in the figure, the relationship between these two angles are alternate exterior angles, so that means they are congruent. To figure out the value of x, simply equate the two angle measurement to each other and simplify.

Given:

  • (7x - 20)°
  • (4x + 16)°

Solution:

  • 7x - 20 = 4x + 16
  • 7x - 4x = 20 + 16
  • 3x = 36
  • x = 36/3
  • x = 12

Answer:

  • The value of x is Letter C. 12.
