Answer 2

Answer:

Step-by-step explanation:

let the angles be,

1x,4x and 5x

By angle sum property,

$\large\tt \angle A+ \angle B+ \angle C =180^{\circ}$

$\large\tt x+ 4x+ 5x =180^{\circ}$

$\large\tt 10x =180^{\circ}$

$\large\tt x =18^{\circ}$

Put the value of x,

$\angle 1= x=18^{\circ}$

$\angle 2= 4x=72^{\circ}$

$\angle 2= 5x=90^{\circ}$
