Question

If one angle of a triangle is equal to the sum of the other two angles of the triangle then find the measure of the largest angle of the triangle.​

Answer 1

Answer:

I think Correct answer is 90

Answer 2

Answer:

Let the largest angle be x.

let the other two angels be y,y (since they are equal)

A.T.Q ,

x = y + y

x = 2y

since the sum of interior angles of a triangle is 180°

Therefore , x + y + y = 180°

x + 2y =180°

x + x = 180° ( x = 2y )

2x = 180°

x = 90°

Therefore , the largest angle is 90°.
