Question

in angle abc,angle a =76Digree and angle b=48digree then angle c=? option a 66diger B is56digree c is 124digree d is 28digree​

Answer 1

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°
