Question

If a triangle has angles that fit the ratio 4:3:2, what would be the measure of each of the angles?

Answer 1

80,60,40

Explanation:

The three angles of a triangle add to 180

Multiply the ratio by x

The angles are 4x, 3x, 2x

Add them together

4x+3x+2x = 180

Add like terms

9x = 180

Divide by 9

9x/9 =180/9

x = 20

The angles are 4x = 4(20) = 80

3x= 3(20) = 60

2x= 2(20) = 40
