Answer:
Given that,
The two interiors of a triangle are in the ratio =2 : 3
One of the exterior angle = 80 degrees
Let the two angles be 2x and 3x
(we know that the sum of two interior angles is equals to one exterior angle)
So that,
= 2x + 3x = 80
= 5x = 80
= X = 80/5
= X = 16
Then the two angles are :
= 2x = 2(16) = 32
= 3x = 3(16) = 48
Therefore the value of two angles is 32 and 48
