Re: In the figure above, lines l1 and l2 are parallel. What is the value [#permalink]
In the figure above, lines l1 and l2 are parallel. What is the value of x ?

(1) y = 87, X+y =180 as both are supplementary, so X = 93, sufficient.
(2) z = 93, sufficient. X and z are corresponding angles of two parallel lines.

Imo. D
