Question

In the given figure, if AB // DE, ZBAC = 35º and Z CDE = 53º, find ZDCE. B А 35° C 53° D E​

Answer 1

Step by Step Explanation

∠AED=∠BAC (alternate interior angles)

⇒∠AED=35

0

⇒∠CED=35

0

InΔDEC

∠CDE+∠DCE+∠CED=180

0

(by angle sum property)

53

0

+∠DCE+35

0

=180

0

∠DCE+88

0

=180

0

∠DCE=180
