Question

The angle of a triangle are in ratio 1 3 5 Find the measure of the angle​

Answer 1

SOLUTION :

The angle of a triangle are in ratio 1:3:5,

Let the measure of triangle be x,3x,5x

=> x + 3x + 5x = 180

=> 9x = 180

=> x = 180

9

=> x = 20

First angle = 20 degree

Second angle= 20 × 3 = 60 degree

Third angle = 20 × 5 = 100 degree

Answer 2

let ratio be X

A/Q

X+3x+5x=180

9x = 180

x=180/9

x=20

first angle is 20

second angle is 20 *3= 60

third angle is 20*5= 100
