Simple interest formula is
I=P*(rt)
P=70
t=12
3%=0.03
r=0.03
I = 70*0.03*12= 25.2
The answer is X=27 degrees
Steps-
90-63=27
33.967741935483870967741935483871 just divide the years into the wins and you will have wins per year. This answer has to be rounded but I like to give the entire answer as if you did this yourself
Hope this helps some
