Question

in ABC if Angle B is equals to 76 and angle C is equals to 48 find angle A

​

Answer 1

∠ A + ∠ B + ∠C = 180° {Angle sum property of triangle}

∠A + 76° + 48° = 180°

∠A = 180° - 124°

∠A = 56°

Answer 2

<A + <B + <C = 180⁰

<A + 76⁰ + 48⁰ = 180⁰

<A + 124⁰ = 180⁰

<A = 180⁰ - 124⁰

<A = 56⁰
