Question

The ratio of the angles in a triangle is 3:10:7, what is the measure of the smallest angle

Answer 1

27°

Explanation:

Let the measure of the angels be 3x, 10x, 7x.

`3x + 10x + 7x = 180 \degree \\ \\ 20x = 180 \degree \\ \\ x = (180 \degree)/(20) \\ \\ x = 9 \degree \\ smallest \: angle \: = 3x \\ \\ = 3 * 9 \degree \\ \\ = 27 \degree`
