2
given ratio,

3:2:7

let us take unknown number =x

so, 3x+2x+7x

sum of all angles in the triangle= 180

so,

3x+2x+7x =180

12x =180

x=180/12

x=15

each Angles

3x=3×15=45

2x=2×15=30

7x=7×15=105

therefore,
all angles=45,30,105....

let the unknown angle be=x
sum of all angles=180°
then
3x+2x+7x=180
12x=180
then
x=180/12
x=15
put x in 3x,2x&7x
3×15=45°
2×15=30°
7×15=105°
hence angles are 45°,30°,105°
