Question

one of the exterior angles of a triangle is 125 degrees and the interior opposite angles are in the ratio 2 :3 find the angles of the triangle

Answer 1

If one exterior angle is 125,then the vertically opposite angle will Interior angle of (180-125=55°)

Let the other two angles be 2x and 3x

Then.

180=55+2x+3x

180-55=5x

125=5x

125/5 =x

25=x

Then the angles are

2*25=50°

And other angle =3*25=75°


I hope this will help you
