Given :- AB//CD , ANGLE BAE = 110 , ANGLE ECD= 130to find :- xconstruction :- draw a line MG intersecting E and parallel to AB & CD , divide x into angle 1 and angle 2 solution:- angle 1 = 180 - 110. ( CO interior angles) angle 1 = 70° angle 2 = 180 - 130 ( Co interior angles ) angle 2 = 50° now, X = angle 1 + angle 2X = 70 + 50X = 120°
