Can anyone please help me with this hard math?
Karsten and Jorge are playing a game of Laser Tag at Karsten's birthday party. They are in a room that is 30 feet wide and 60 feet long. The room has obstacles that block the laser beams, but it also has walls which reflect the beams.
As shown in the diagram below, Karsten is standing 6 and 12 feet from the two walls in one corner of the room. Jorge is standing 8 and 15 feet from the two walls in the opposite corner, and several obstacles between the boys are preventing direct shots.
Karsten decides that he can hit Jorge by bouncing a beam off wall AB. He knows that the slope of his reflected beam will be the negative of its slope before it hits the wall.
How far along the wall from corner A should Karsten shoot for his reflected beam to hit Jorge?

And Can anyone explain how to solve this problem because it is too complicating for me.
When is this shite ever used in real life? LOL ~ I'm sure in the heat of the moment of playing laser tag, someone is gonna stop and figure all this out before shooting the lasers.
Sorry I couldn't help. Nice picture, btw.
