Question

19. In the adjoining figure, if AB//DE, angle BAC = 35º and angle CDE = 53º. Then find angle DCE.
​

Answer 1

Answer:

92°

Step-by-step explanation:

Since AB and DE are parallel

BAC=CED=35°(alternate interior angles)

So according to angle sum property of triangle

Sum of all interior angles =180

CED+CDE+DCE=180°

35+53+DCE=180

88+DCE=180

DCE=180-88

DCE=92°
