Question

one of the exterior angle of a triangle is 105the interior ooposite angles are in the ratio 2:5 .Find the angles of the triangles​

Answer 1

Step-by-step explanation:

given that exterior angle is =105. and the ratio between two angle s = 2xAnd5x. then 2x+5x=105 ,x=105/7 ,x=15. and substitute the value then 30,75,75

Answer 2

Answer:

Let the angles be 2x and 5x

Measure of External angle = Sum of opposite 2 interior angles

105 = 2x+5x

7x = 105

x = 15

2x = 30

5x = 75

Thus the two angles will be 30 degree and 75 degree.
