Best Answer:
Do you need specific numbers or a general description?

If a general description will do:

At a launch angle of 90 degrees, the range will be zero since the projectile will travel straight up and back down.

As the launch angle is reduced, the height of the trajectory will be reduced and the range will increase as more energy drives the projectile downrange and less drives it skyward. (Trajectories from firing angles greater than 45 degrees are characterized by large max height and shorter range.)

At a 45 degree angle, range is maximized.

Once past 45 degrees, the range starts to fall again as the trajectory's reduced height reduces the flight time of the projectile.

At a launch angle of 0 degrees, the range will be limited by the height of the launcher over the surrounding ground. The projectile will quickly lose any altitude it has, limiting the range significantly.
