Question

One angle in a triangle measures twice the smallest angle, whereas the largest angle is nine times the smallest angle. Find the measures of all three angles.

° (smallest value)
°
° (largest value)

Answer 1

Explanation:

Let the smallest angle be x

2nd angle = 2x

3rd angle = 9x

By angle sum property

x+2x+9x=180°

x=180/12

x=15

Three angles are 15, 30 and 135
