Question

One of the exterior angle of a triangle is 120 degree and the interior opposite angle are in the ratio 4 ratio 2 find the angle of the triangle

Answer 1

Step-by-step explanation:

let the ratio of interior opp. angle be 4x and 2x.

A/q

exterior angle 120 degree = sum of int. opp. angle

120 = 4x + 2x

120÷6 = x

20 = x

4x = 4×20 = 80

2x = 2×20 = 40

Answer 2

Answer:

Step-by-step explanation:

let the ratio of interior opp. angle be 4x and 2x.

A/q

exterior angle 120 degree = sum of int. opp. angle

120 = 4x + 2x

120÷6 = x

20 = x

4x = 4×20 = 80

2x = 2×20 = 40
