I believe d has to be the right answer. I solved the problem backward so the explanation would be confusing. Try subtracting the 22 degree angle from 180.
I think it is x to the 14th power

I=k/d^2
4=k/d^2 and 1=k/64 so if we divide the first by the second we get:
4/1=(k/d^2)/(k/64)
4=(k/d^2)*(64/k)
4=64/d^2
d^2=64/4
d^2=16
d=4 meters
