Question

in the adjacent figure, AB//CD. Determine _|_ a​

Answer 1

Answer:

let angle ABQ = 38° and angle CDQ=35° and a=X

by question we get,

angle ABQ+angle CDQ+X =180°( straight line)

38°+35+x°=180°

73°+x=180°

x=180°-73°

x=107°

therefore X=180°

hope it helps and if there's a mistake do correct me and forgive me...
