Answer 1

Step-by-step explanation:

We know that in triangle ABC Angle A + Angle B + Angle C = 180°...(3)

Angle A + Angle B = 144°...(1)

Angle A + Angle C = 124°...(2)

Add (1) and (2) => 2Angle A + Angle B + Angle C =268° => Angle A +(Angle A+ Angle B+ Angle C) =268° => Angle A +(180°) = 268° => Angle A =268°-180°= 88°. So substitute Angle A as 88° in equation (1) we get

Angle B = 144°- Angle A = 144°-88°= 56°. Option(1) is the correct answer. Hope it helps you.
