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

Correct Answer

(1) 10
(2) 55
(3) 125

Explanation

  1. To find x, use the vertical angles rule where ∠ZYQ and ∠XYP are vertical, then their measures are the same
    • 2x + 35o = 6x - 5o
    • 4x = 40o
    • x = 10o
  2. Substitute x in the measure of angle ∠ZYQ,
    • m(∠ZYQ)= 2x + 35o = 2 * 10o + 35o = 55
  3. ZYQ and ∠PYQ are supplementary, then
    • m(∠PYQ) = 180o - 55o = 125o
