A gun shoots bullets that leave the muzzle at 247 m/s. If a bullet is to hit a target 161.4 m away at the level of the muzzle, the gun must be aimed at a point above the target. (Neglect air resistance.)

________________________________________

How far above the target is this point if the angle the gun makes is less than 45degrees?

The additional question is, same question above but if angle is more than 45degrees.

For projectile motion problems, I know once we know the angle, then we take sin(angle)v to find the velocity for y-coordinate system, then solve for distance or time..whatever. But for this question, it's so ambiguous, angle is less than or greater than.. i have no idea what to do, help me out.
