Answer 2

Step-by-step explanation:

lf you mean,

The angle of a triangle are in the ratio 1:4:5, Find the angles of the triangle.

Let the angles of a triangle x:4x:5x

⇒x+4x+5x=180°

by angle sum property of a triangle.

⇒10x=180°

∴x= 180°/10=18°

Hence x=18°

4x=4×18°=72

and 5x=5×18° =90

The angles are 18°,72°and 90
