Question

In fig if ab parallel to de angle bac is equal to 35 and angle cde is equal to 53 find angle dce

Answer 1

Can u please provide me the figure of this question?

Answer 2

Hello mate ☺

____________________________

Solution:

It is given that AB∥DE. Therefore, ∠BAC=∠DEC              (Alternate Interior Angles)

∠BAC=35°      (Given)

Therefore, ∠DEC=35°

In ∆DCE, we have

∠DEC+∠CDE+∠DCE=180°         (Sum of three angles of a triangle =180°)

⇒35°+53°+∠DCE=180°

⇒∠DCE=180°−35°−53°=92°

I hope, this will help you.☺

Thank you______❤
