Find the value of x:

  • 7x - 2 = 55 + 4x (as corresponding angles)
  • 7x - 4x = 55 + 3
  • 3x = 57
  • x = 19

Find the value of y:

  • y = 7x - 2 (as alternate exterior angles)
  • y = 7*19 - 2
  • y = 131

#30

Find the value of x:

  • 14x - 34 = 9x + 1 (as alternate interior angles)
  • 14x - 9x = 1 + 34
  • 5x = 35
  • x = 7

Find the value of y:

  • y + (9x + 1) = 90 (as complementary angles)
  • y = 90 - 9*7 - 1
  • y = 26
