  1. x =
  2. m(∠ZYQ) =
  3. m(∠PYQ) =

Correct Answer

(1) 25
(2) 115
(3) 65

Explanation

  1. To find x, use the vertical angles rule where ∠ZYQ and ∠XYP are vertical, then their measures are the same
    • 4x + 15o = 7x - 60o
    • 3x = 75o
    • x = 25o
  2. Substitute x in the measure of angle ∠ZYQ,
    • m(∠ZYQ)= 7x - 60o = 7 * 25o - 60o = 115
  3. ZYQ and ∠PYQ are supplementary, then
    • m(∠PYQ) = 180o - 115o = 65o
