Question

the three angles of a triangle are in the ratio 1:3:5. find all the angles of a triangle ​

Answer 1

Answer:

let ratio = 1x, 3x, 5x

sum of all angle of triangle = 180

= x+3x+5x = 180

9x = 180

x = 180/9

x = 20

so, 1x = 20

3x = 3*20= 60

5x = 5*20= 100

Answer 2

Step-by-step explanation:

given ratio =1:3:5

In triangle sum of all angles =180

1x+3x+5x=180

9x=180

x=180/9

x=20

1x=20

3x=3×20

=60

5x=5×20=100
