Question

In triangle Abc, if angle c = angle A +b upon 2 then, find angle c​

Answer 1

Answer:

We know that, in a triangle,

A+B+C=180° (Angle Sum Property)

So, A+B+(A+B)/2=180°

So, [2(A+B)+A+B]/2=180°

So,2A+2B+A+B=2×180°=360°

So, 3(A+B)=360°

So,A+B=360°/3=120°

So,A+B=120°

So, C=(A+B)/2=120°/2

So,C=60°
