Get Angle Between Player & Projectile Given two Velocities Vectors/Distance


Let me just start of with saying that trigonometry is not my strong suit, which is why I am reaching out for help in this very specific trig problem I encountered while developing my game today!

I am trying to get the angle between a projectile and a player, given the projectiles velocity & distance from player, and also given the velocity the player has. The angle would be used in order to contact the player at a given point. I would also get the distance in which the player would travel in order to contact the projectile from the given angle!

Any sort of help would be appreciated,
Thank you!
