( Fire the ball or lob it :)

Vi = Vo sin T

u = Vo cos T

v = Vi - 9.8 t

v at top = 0

t = Vi/9.8 = (Vo/9.8)sin T

2 t = time in air (Vo/4.9) sin T

range = u (2 T)

= Vo cos T (Vo/4.9) sin T

= (Vo^2/4.9) cos T sin T

if T = 30

sin T = .5 and cos T = .866

but if T = 60

sin T = .866 and cos T = .5

same range
