Just before any of you say anything; Yes, I posted this a few days ago, but I didn't do the diagram correctly so I'll just post this new thread.

Okay, so :

I'm trying to work out the angles on the triangle and I'm having a little bit of difficulty. I tried working it but I'm not getting anywhere. Would the angle at the right of the 65 be 25? And would the one opposite to the "25" be "90"?

And by the way, the most important angle that I really need to get is the one at the tangent.

Please, please, please help!
