In the given figure, POQ is a line, then the value of x is
Here, 40∘+4x+3x=180∘ [since POQ is straight line] 7x=180∘−40∘ x=1407=20∘ Hence, the value of x is 20∘
In the given figure, if AB||CD,∠APQ=50∘ and ∠PRD=127∘, the value of y is:
In the given figure, if AE∥DC and AB=AC, the value of ∠ABD is
(a) 70∘
(b) 110∘
(c) 120∘
(d) 130∘
