Question

The angles of a triangle are in the ratio 3:5:7 find the measure of these angles



plz tell fast ​

Answer 1

Answer:

36°, 60°, 84°

Step-by-step explanation:

Let the measure of angles be x

Ratio of angles = 3 : 5 : 7

Sum of all angles = 3x + 5x + 7x

                             = 15x

Measure of all the angles of a triangle = 180°

15x = 180°

x = 180/15

x = 12°

3x = 3 × 12

    = 36°

5x = 5 × 12

    = 60°

7x = 7 × 12

    = 84°

∴ The measure of angles of a triangle who are in the ratio 3 : 5 : 7 is 36°, 60°

   and 84°
