Question

In the given figure, if angle ABD = 110° and angle BAC = 50°, then angle BCA = ?​

Answer 1

Pls let us take a look at the given figure first

Answer 2

Step-by-step explanation:

Given:

• angle ABD= 110° and
• angle BAC = 30°

To find:

the measure of angle BCA= ?

Solution:

Ext. angle of a ∆ is equal to the sum of the two interior opp. angle s.

Since, ABD = Angle BAC + angle BCA

=> 110° = 50° + angle BCA

=> Angle BCA = 110° - 50°

=> Angle BCA = 60°

Hence, the measure of angle BCA is 60°.

Hope this helps.
