Optima Learn · Accepted Answer

Understanding Given two parallel lines l1 l2 with XAB 140 , and OA, OB bisecting XAB and ZBA respectively, we need to find the marked angle x at point O. Analyzing Since XAB 140 is the interior angle at A, and l1 l2, the co-interior angle ABZ 180-140 40 . Since OA bisects XAB, OAB 140 2 70 . Since O
