Hey all 
I'm going insane because I can't think of how to do this...
I can't for the life of me get this straight... I have a triangle that I'm trying to solve for the hypotenuse, angle theta is 70 degrees and I know the adjacent leg is 7500. Cosine SHOULD solve for the hypotenuse, right (adjacent/hypotenuse)? I can't get it to solve for the hypotenuse.
I set it up like this:
cos70 = 7500/y
I need to get the 7500 on the side with the cos70, but wouldn't I have to multiply the right by 1/7500 to cancel it on that side for y (hypotenuse)?
Any help would be appreciated, I'm running into this over and over with my probelms.
Thanks!
