Question

One of the angles of the triangle is equal to the sum of other two angles.What is the measure of that angle?​

Answer 1

That angle is 90°

a + b = c

a + b + c = 180°

2 [ a + b ] = 180°

a + b =90°

Hence c = 90°

Answer 2

ans.=90 degree

let, larger angle be x

x=y+z______1. (from given)

In triangle,

x+(y+z)=180

x+(x)=180. ______(from 1.)

2x=180

x=90
