Question

one of the exterior angles of a triangle is 125° and the interior opposite angle are in the ratio 2:3.Find the angles of the triangle.​

Answer 1

As we know the sum of two interior opposite angles is equal to exterior angle.

Let the angles be x and 4x.

so,

x+4x=125

5x=125

x=125/5

x=25

Therefore,

1st angle is x=25 degrees

2nd angle is 4x=4∗25=100 degrees.

Answer 2

Using exterior angle property
2x+3x=125
5x=125
X=25
So angle are
50, 75, 55
