Answer:

  • value of x = 15
  • m∠A = 123°
  • m∠B = 57°
  • value of y = 12
  • m∠C = 113°
  • m∠D = 113°
  • m∠E = 67°

Explanation:

3x + 12 = 5x - 18 (alternate exterior angles)

5x - 3x = 12 + 18

2x = 30

x = 15

m∠A + (3x+12) = 180 (supplementary angles)

m∠A = 180 - (3×15 + 12)

= 123°

m∠B = 3x + 12 (vertical angles)

= 3×15 + 12

= 57°

(6y-5) + (10y-7) = 180 (same side interior angles)

16y - 12 = 180

y = 192 ÷ 16

= 12

m∠C = 10y - 7 (alternate interior angles)

= 10(12) - 7

= 113°

m∠D = 10y - 7 (vertical angles)

= 10(12) - 7

= 113°

m∠E = 6y - 5 (corresponding angles)

= 6(12) - 5

= 67°
