Question

an exterior angle of triangle is 130 degree and its interior opposite angles are in a ratio of 3:2. find the angle of the triangle solution

Answer 1

exterior angle = sum of two interior opposite angle.

therefore ,

130° = 3x + 2x

130° = 5x

x = 130°÷5

x= 26°

the angles are

3×26 = 78°

2×26 = 52°
