In a ∆ABC , angle A + Angle B = 125° and Angle B + Angle C = 150° . Find all the angles of ∆ABC.

Given that,

In triangle ABC

We know,

Sum of all interior angles of a triangle is supplementary.

On adding equation (1) and (2), we get

On substituting the value in equation (1) and (2), we get

Also, from equation (2), we get

Hence,

it goes right
