Three angles are color(purple)(40^@, 60^@, 80^@ respectively.

Explanation:

Sum of the three angles of a triangle = 180^@

Given the three angles are in the ratio 2:3:4

Let the angles be hat A, hat B , hat C

hat A = (2/(2+3+4))^180 = color(purple)(40^@

hat B = (3/(2+3+4))^180 = color(purple)(60^@

hat C = (4/(2+3+4))^180 = color(purple)(80^@
