Question

calculate the angle of a triangle, if they are in the ratio 3:4:5​

Answer 1

Answer:

let common rato be x

1st angle = 3x

2nd angle=4x

3rd angle = 5x

by angle sum property of triangle

a+b+c=180°

3x+4x+5x=180

12x=180

x=180/12

Answer 2

Answer:

Step-by-step explanation:

3:4:5=3x:4x:5x

3x+4x+5x=180 degree           (Angle sum property)

12x=180

∴x=15

Angle 1=45

Angle 2=60

Angle 3=75
