Question

in the given figure BC PARALLEL DE if angle ACE IS EQUAL TO ANGLE CDE =90 degree and angle ACB =30 degree the n the measure of DCE​

Answer 1

Answer:

DCE=∠EAB (Alternate angles as AB∣∣DE and AE is transversal)

∠DEC=35

∘

In △DCE, we have

∠DCE+∠CED+∠CED=180

∘

(Angle sum property)

∠DCE+35

∘

+53

∘

=180

∘

∠DCE=180

∘

−88

∘

=92
