most cell phone calculators are capable of this. Make sure you use the same units.

For example 1000 yards line of sight 600ft vertical equals 200yards vertical.

((1000)^2-(200)^2)^.5 = 980 yards

if you want to know the angle that is then take arctan(200/1000) = 11.3 degrees
Hey Thanks alot, i figured thier must be some formula. Thats a little complex for me but i did eventually get it right after i found parrethesees on a scientific calculator on computer, i got an answer of 979.79589711327123927891362988236 yards so i imagine i computed it correctly.
Very interesting, will be fun to experiment with while out target practicing.

Yeah, you did it right, I just rounded a little.
