Answer:

A: 75°

B: 60°

C: 45°

Step-by-step explanation:

The sum of ratio units is 5+4+3 = 12. Comparing that to the sum of angles in a triangle, 180°, you see that each ratio unit must stand for 180/12 = 15 degrees.

Multiply the ratio of angles by 15° and you get the actual angles:

A : B : C = 75° : 60° : 45°

Angle A is 75°, Angle B is 60°, Angle C is 45°.
