Question

the angles of a triangle qre in the ratio 5: 6: 7: . find the angles.​

Answer 1

Step-by-step explanation:

let the angles be 5x , 6x and 7x

the sum of all angles in a triangle = 180°

5x + 6x + 7x = 180•

18x = 180°

x = 180/18

x = 10°

so the angles are.....

5x = 5 × 10 = 50°

6x = 6 × 10 = 60°

7x = 7 × 10 = 70°

Answer 2

let the angles be 5x,6x,7x

A.T.Q

5x+6x+7x=180°

18x=180°

x= 180/18

=10°

5x=5×10=50•

6x=6×10=60°

7x=7×10=70°
