Question

The angles of triangle are in the ratio 3:5:7 .Find the measures of the three angles.
(Answer in explaination)

Answer 1

Answer:

36°,60°,84°

Step-by-step explanation:

The sum of all angles of a triangle is 180°.

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

3x+5x+7x = 180°

15x = 180°

x = 180/15

x = 12

So the angles are -:

3*12 = 36°

5*12 = 60°

7*12 = 84°
