Question

the angles of a triangle in the following case.
the angles are in the ratio 5: 3: 10​

Answer 1

sum of all the ANGLES in a ∆ is =180°

so,

5x+3x+10x=180

18x=180

x=180/18

x=10°

now,

5x=5*(10)=50°

3x=3*(10)=30°

10x=10*(10)=100°

the ANGLES are=30°,50°,110°

Answer 2

let angle of triangle are 5x,3x,10x

we know sum of all angles of triangle =180

5x+3x+10x=180

18x=180

x=180/18=10

1st side=5x=5×10=50

2nd side=3x=3×10=30

3rd side=10x=10×10=100
