Question

the angles of the triangle sre in a ratio 1:3:5.Determine the angles

Answer 1

helo

given angles are in ratio 1:3:5

let first angle be x so second will be 3x and third will be 5x

sum of all angles is 180 in a triangle

so
x+3x+5x= 180

9x=180

=>x=20°

so first angle is 20°

second is 3×20=60°

third angle is 5×20° =100

thanks !!

Answer 2

Let the angles be x, 3x,5x
Sum of the angles in a triangle =180
So, x+3x+5x=180
9x=180
X=180/9=20

Therefore 1st angle =20
2nd angle 3x=3(20)=60
3rd angle 5x=5(20) =100
