Question

In a triangle ABC, <B = 50*, <C = 60*. Find <A?
​

Answer 1

Answer:

In triangle ABC, ∠A = 70°

Step-by-step explanation:

Given in Δ ABC ,  ∠B =50°, ∠C= 60°

We need to find ∠A

In a triangle sum of three angles = 180°

            ∠A+ ∠B+ ∠C = 180°

           ∠A+ 50° + 60°= 180°

          ∠A + 110°= 180°

            ∠A = 180-110° = 70°

 In triangle ABC , ∠A = 70°

Answer 2

Answer:

70 is the right answer of this question
