Answer:

The angles are 45°, 60° , 75°

Step-by-step explanation:

<h3>Angle sum property:</h3>

Sum of all the angles of a triangle is 180°.

Equation:  

     3x + 5x + 4x = 180

Combine like terms,

                   12x = 180

                      x = 180/12

                      \sf \boxed{x = 15}

3x = 3 *15 = 45°

5x = 5* 15 = 75°

4x = 4 *15 = 60°
