Question

In ∆ABC, ∠A = 670

, ∠B = 480

, ∠C = ………..​

Answer 1

290 is the answer of 3 one

Answer 2

Answer:

∠A= 56°

Step-by-step explanation:

Given:-

∠B=76°

∠C=48°

∠A=?

As we know that, sum of all angles of a triangle is 180°.

∴∠A+∠B+∠C=180°

⇒∠A+76°+48°=180°

⇒∠A+124°=180°

⇒∠A=180°−124°

⇒∠A=56°
