Question

in triangle a 79 b 48 find the measurement for c​

Answer 1

Answer:

Given:-

∠B=76°

∠B=76°∠C=48°

∠B=76°∠C=48°∠A=?

∠B=76°∠C=48°∠A=?As we know that, sum of all angles of a triangle is 180°.

∠B=76°∠C=48°∠A=?As we know that, sum of all angles of a triangle is 180°.∴∠A+∠B+∠C=180°

∠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°

∠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°

∠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°

∠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°
