Question

the angles of a triangle are in the ratio 5:4:3 fing the measure of each angle

Answer 1

5x+4x+3x=180degrees
12x=180
x=180÷12
x=15
5x=75
4x=60
3x=45
75,60 and 45 are the angles

Answer 2

$\huge\color{Purple}{Hey\: Mate!!}$

here is your answer:

Let the angles be 5x, 4x, and 3x.

then, 5x+4x+3x= 180° (Sum of angles Of a triangle is 180°)

therefore, 12x=180°

X=180\12
X=15

Hence, the angles are:
3x=3×15=45°
4x=4×15=60°
5x=5×15=75°

hope it helps you!!
