How do I find a coordinate knowing distance and angle from a certain point?

i'm making a 2d game where someone can make bridge-like structures like iceman. he shoots out a string of bullets with gravity (called Sprite9), which turn into platforms (called Sprite8) on contact with another solid. i am trying to spawn these platforms in 5 pixels from the contact, at the angle of motion of the bullet. i'm using "system>create object" for this so it wants me to plug in an x and y coordinate for the new Sprite8.

I hope someone can help.

Whatever the solid is that the bullet is colliding with, you can use the spawn action for that solid to spawn the platforms on the solid, or at an imagepoint/particular location on that solid. If it's 5px away then move an imagepoint 5px away and spawn them there.

Yeah, you can create the object at the point of collision and then use "Move 5px at angle". Or use these formulas:

newX = startX+distance*cos(angle)

newY = startY+distance*sin(angle)
