Question

the angles of a triangle are in the ratio 3:5:7. find the measure of the three angles.​

Answer 1

let the angles be 3x,5x and 7x

3x+5x+7x=180

15x=180

x=180/15=12

the angles are 45,60 and 84 degrees

Answer 2

Step-by-step explanation:

Let the angles be 3x, 5x, 7x

sum of angles of triangles = 180

3x +5x +7x =180

15x = 180

x = 180/15

x = 12

the measure of three angles are

3x = 3X15 = 45

5x = 5X15 = 75

7x = 7X15 = 105
