Solve for x and y, values are in cm. X was easy, Y couldn't wrap my brain around it within like 5 minutes of thinking so i thought you guys could help out.

ABC=90
CBD=90

use trig to find ACB

minus from 180 to get BCE

BCED is a quaderilateral. you have 2 right angles too

go figure
Get off this damn forum and play your damn guitar.

Use Pythagoras's theorem to find x.

Then use sin(angleBAC)=x/9 to find the angle BAC.

Then use cos(BAC)=y/12 to find y.
