Question

in triangle abc if angle b is equal to 76 degree and Angle C is equal to 48 degree find angle A

Answer 1

180 degree = angle A + angle B + angle C

180 degree = angle A + 76 degree + 48 degree

180 degree = angle A + 124 degree

180 degree - 124 degree = angle A

56 degree = angle A

Hope its helps!!

Answer 2

A+b+c=180
a+76+48=180
a+124=180
a=180-124
a=56ans
