Question

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

Answer 1

Answer:

75° is the correct answer☑

Step-by-step explanation:

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° ans.
