Question

If angles of a triangle are in the ratio 1: 3: 5. Find the value of each angle.​

Answer 1

Question :---- we have to find each angle...

Given :--- their ratio is 1:3:5 ....

let angles of ∆ are x , 3x and 5x ...

And,

we know that, sum of all angles of ∆ = 180°

so,

x+3x+5x = 180°

9x = 180°

x = 20°

so,

all angles will be :------

x = 20°

3x = 60°

5x = 100°

(Hope this helps you)

Answer 2

Step-by-step explanation:

Given angles in a triangle are in ratio of 1:3:5. Let the angles be 1x,3x and 5x. We know that the sum of the three angles in a triangle is 180°. Then,. 1x+3x+5x= 180°. 9x=180°. x=180/9. x=20. The angles are:. 1x=1(20)=20°. 3x=3(20)=60°. 5x=5(20)=100°. So the angles are 20°,60°,and 100°
