Step-by-step explanation:
ok so as u know the angles of a triangle add up to 180.
So we will be using that for help.
S+R+T=180
12x+13x+12x-4+2-3=180
37x-5=180
37x=185
x=5
Now we will plug in the value for x to find each angle
S= 13(5)-4
=61
T=12(5)-3
=57
R=12(5)+2
=62
Hope this helped:)

62,57,61
Step-by-step explanation:
(12x +2) + (12x-3 ) + (13x-4) = 180
37x = 180 -2 +3+4
37x = 185
x = 185/37 = 5
One angle =(12x +2) = 62
Second angle =(12x-3 ) = 57
Third angle = (13x-4) = 61
