AB is parallel to CD...FIND X!!​

Answer»

ANSWER :-

AB||CD ( given)

so DRAW TP||AB||DC

Angle BAT + angle ATP = 180 ( Interior angle on the same side of transversal )

140 + ATP = 180

ATP = 180 - 140

ATP = 40 --------- ( i )

again

angle DCT + CTP = 180 ( interior angle on the same side of transversal)

150 + CTP = 180

CTP = 180 - 150

CTP = 30 ---------- (II)

now add equation i and ii

ATP + CTP = X

40 + 30 = x

70 = x

hence , x = 70

hope it will help you☺☺
