Question

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

Answer 1

first angle is 20, second is 60 and 3rd is 100

Step-by-step explanation:

1x+3x+5x= 180°

9x= 180°

x=180/9

x=20°

so 20 ×1= 20

20×3=6

20×5=

Answer 2

Let angles of triangle be x, 3x and 5x

As we know that

⇒Sum of all angles of triangle = 180°

 ⇒ ∴ x + 3x + 5x = 180°

 ⇒9x = 180°

x = 20° , 3x = 60°  and 5x = 100°
