Hey guys,

I'm trying to find the way to solve a very simple problem (I know the answer, but I don't know how to get there). I've found very similar ones on the internet and searched youtube, google, etc; but still w/o any luck. I wonder if anyone can help me (the answer, according to the textbook is 13).

Basically, it is a right triangle inside a right triangle, with the opposite sides equal 24 and 12 (the smaller one is half the size of the bigger one). I need to find the distance between A and Y (the hypothenuse, which I assume is half of the bigger one, or a AW).

It's driving me crazy...

Best regards!
