Applying the definition of linear pair, the value of x is: D. 40.

What is a Linear Pair

  • A linear pair is a set of angles on a straight line.
  • Straight line angle = 180 degrees.
  • Linear pair of angles add up to 180 degrees.

Therefore:

x + (4x - 20°) = 180°

  • Solve for x

5x - 20 = 180

5x = 180 + 20

5x = 200

  • Divide both sides by 5

x = 40

Therefore, applying the definition of linear pair, the value of x is: D. 40.
