Default Re: OT: would anyone happen to know how to calculate bouncing a ball off an angled box?

Easy, the incoming and outgoing angles are always equal. I can make a drawing when I get home, but for now imagine an underlined V. The underline is the box surface and the V is the ball's trajectory. Now the angle from the left side of the underline to the left of the V must be equal to the angle from the right side of the underline to the right side of the V.

This in 2-D, which is what you are using, right ?
