Q. 154.8( 4 Votes )

# In a triangle ABC, ∠B = 50° and ∠A = 60°. Suppose BC is extended to D. Find ∠ACD.

Answer :

It is given that in ∆ ABC,

B = 50° and A = 60°

Here, ACD is an external angle. We know that an exterior angle of a triangle is always larger than either of the interior opposite angles.

⇒ ∠ACD = A + B = 50° + 60° = 110°
