$\red{\boxed{ \huge \fbox\pink{A}\fbox\blue{ñ}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r} } }$

Let the angles be 2x ,3x and 4x respectively

We know, sum of angles is 180

So,

→ 2x + 3x + 4x = 180

→ 9x = 180

→ x = 180/9

→ x = 20

Angles :-

2x = 2 × 20 = 40°

3x = 3 × 20 = 60°

4x = 4 × 20 = 80°
