# getting an angle with respect to distance

need help with a problem I created.

Someone is running at 18mph west, toward B from C, the distance between A and C is 0.2 miles Someone shoots a paintball that travels at 190 mph, from A toward B, predicting where C would be. At what angle would A have to shoot? From A to C is 90 degrees. Assume time starts right after the gun is shot

How do I get the angle (degrees) that the gun should be shot to hit the target? (no sway, air resistance, etc)

Would this be enough information to get a angle? Any help would be appreciated I can change the way I setup the problem

In order for the paintball and the runner to be in the same place at the same time, you require the component of velocity of the paintball perpendicular to the initial displacement to be the same as that of the runner. Therefore you require $$190\sin \theta=18$$ Note that the actual initial distance $0.2$ is not relevant. All this assumes velocities are constant, and they set off simultaneously.
