Hey Mate ! Here's your answer...

Answer:

100°

Step-by-step explanation:

In triangle ABC

Angle A = 50°

Angle B = 70°

Angle C = 180°- (Angle A + Angle B)

= 180° - (50°+70°)

= 180° -120°

= 60°

(As sum of all angles of triangle is 180°)

Angle ACD = 60°/2 = 30°

(CD is the bisector of Angle C)

Angle ADC = 180° - (Angle A + Angle C)

= 180° - (50° + 30°)

= 180°- 80°

=100°

Therefore, Angle ADC = 100°
