Question

n the adjacent figure, AB || ED, then the value of x is

Answer 1

Step-by-step explanation:

x = 20

y = 60

z = 120

Step-by-step explanation:

AB ║ CD

=> ∠CPQ = ∠PQR

=> ∠CPQ = 80°

80° + 2x° + 3x° = 180° (Straight line)

=> 5x° = 100°

=> x = 20

80° + 2x° + y° = 180° (sum of angles of a triangle)

=> 40° + y° = 100°

=> y° = 60°

=> y = 60

y° + z° = 180° (Straight line)

=> 60° + z° = 180°

=> z° = 120°

=> z = 120
