Question

In Triangle ABC angle B = 30°, Angle C = 60° AD is the bisector of Angle A. Find the other angles of Triangle ABC, ABD and ACD​

Answer 1

Answer:

In Δ∆ABC,

∠ACD = ∠A + ∠B   (Exterior angle property)

= 70∘ + 40∘          

= 110∘

Hence, the measure of  ∠∠ACD is 110∘.

Question 1:

In the given figure, ∠ACD is an exterior angle of ΔABC. ∠B = 40°, ∠A = 70°.

Find the measure of ∠ACD.

ANSWER:

In ΔABC,

∠ACD = ∠A + ∠B (Exterior angle property)

= 70∘ + 40∘

= 110∘

Hence, the measure of ∠ACD is 110∘.
