Answer» 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°

Answer»

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°
