Question

How to find the value of a?
​

Answer 1

Answer:

a = 55

b = 15

Step-by-step explanation:

WXYZ is a parallelogram with XY ║ WZ

WY is a transversal

⇒ a = 2a - 55              [ alternate angles ]

   ∴ a = 55

XZ is a transversal

⇒ 160 - 8b = 2b + 10        [ alternate angles ]

           10b = 150

           ∴ b = 15
