Answer 1

Answer:

let the angle be x

Step-by-step explanation:

now the angles are given in the ratio

=3:4:5

let the angles be 3x, 4x and 5x

A.T.Q , by using angle sum property of triangle we find that

3x+4x+5x=180°

:- 12x=180°

:- x=15°

now the given angles are

3x=45°

4x=60°

5x=75°

hence angles are in ratio :- 45°:60°:75°
