Question

The angles of a triangle are in the ratio 1:4:5​

Answer 1

Step-by-step explanation:

let the angles be x,4x,5x

by the angle sum property

we get , x+4x+5x=180°

so, 10x=180°

x=18°

therefore the angles are 18°,72°,90°

Answer 2

Answer:

let three angles be 1x, 4x, 5x respectively

A/Q

1x + 4x +5x =180°

10x= 180°

x= 180/10

x= 18

1x= 1*x= 1*18 =18°

4x= 4*x= 4*18 =72°

5x= 5*x= 5*18 =90°
