Question

The measure of three angles of a triangle are in the ratio 5:3:1.
Find the measures of these angles.​

Answer 1

Answer:

5x + 3x + 1x = 180°

9x = 180°

x = 180°/9

x = 20°

So angles are,

5x = 5 × 20° = 100°

3x = 3 × 20° = 60°

1x = 1 × 20° = 20°

Answer 2

5x+3x+x=180

9x=180

x =20

5x=5×20

=100

3x=3x 20

=60

x=20 Ans.
