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,

squares, rhombus, rectangles

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above

step-by-step explanation:
