45°
A
O [a] 64
o [b) 116
O [q] 100
(d) 109​

Answer 1

Answer:

In triangle ABC,

Angle B=180°-(30°+34°)

=180°-64°

=116°

Also,

ANGLE ABC +Angle CBD=180°

(linear pair)

Therefore,

Angle CBD=180-116=64°

Using exterior angle property of triangle, we get

ANGLE CBD + Angle BDE

= AngleCED

=> angle CED=64+45=109°

Option d)109° is correct.
