Question

The angles of a triangle are in the ratio2:3:7.find the measure of each angle

Answer 1

Let the angles be 2x,3x and 7x
2x+3x+7x=180 [Angle Sum Property of a Triangle]
12x=180
x=180/12
x=15
2x=30,3x=45,7x=105
Thus, the angles are (in degrees): 30,45 and 105

Answer 2

let all angle be 3x 2x and 7x
sum of all angles=180
3x+2x+7x=180
12x=180
x=15

so angles are:3x=45
2x=30
7x=105
