Question

one of the exterior angles of a triangle is 130 degree interior opposites angles are in the ratio 2:3 . find the measure of two other angles

Answer 1

Answer:

2x+3x=130°(exterior angle property)

5x=130

x=130÷5

x=26

2x=2×26

3x=3×26

Answer 2

Answer:

One angle=52 2nd angle=78

Step-by-step explanation:

Exterior angle=130

Property=exterior angle=sum of interior opposite angles

Sum of ratios=2+3

1 ratio=130/5=26

Therefore-

1 angle =26x2=52

2nd angle=26x3=78
