I have to admit as i start this i don't know where i'm going. But I know that for any distance short of maximum range ( 45 deg elevation) there are 2 angles enfilade and defilade that will have the same range. we can calculate the total time of flight as follows: T1 is calculated with Vo*Sin(theta)- 1/2* g T1^2 0T1 sqrt(2*Vo*Sin(theta)/g) T1 is the time to max height T2 is the time to return to the ground from max height, since g is the same, T2 T1 Time of flight 2* sqrt(2*Vo*sin(theta)/g) horizontal velocity Vo*Cos(theta) therefore Range Vo*Cos(theta)*2*sqrt(2*Vo*Sin(theta)/g) solve for he values of theta that give the desired range PLEASE check my algebra. I'm good on the hard stuff but get sloppy on the other.
