Question

one of the exterior angles of a triangle is 100° and the interior opposite angles are in the ratio 2:3. find all the angles of the triangle.


My book answer is 64°
Solve this step by step​

Answer 1

Answer:

The interior angle connected with exterior angle 100 will be 180-100=80

The sum of other two angles will be 100.

Those two angles will be: add 2+3=5

(2/5)×100 =40 and (3/5)×100=60

So three angles are 80, 60, and 40
