Question

If in a triangle angles in ratio 1:3:5, then find all angles

Answer 1

Answer:

1x + 3x + 5x = 180°

9x = 180

X = 180/9

X = 20

1x = 20

3x = 60

5x = 100

Answer 2

$\large\underline\mathrm\purple{SolutiON}$

Let the angle be x

As we know that sum of three angle of triangle is equal to 180°

${x+3x+5x=180}$

${9x=180}$

${x}{=}\large\frac{180}{9}$

${x=20}$

So x = 20°

3x = 20×3 = 60°

5x = 5×20 = 100°
