I'm a bit confused on how to find the sin A, cos A, and tan A in this figure presented below:
Since the only given values are 135(side value) and 90 degrees, I'm a bit lost on how to acquire, sin, cos, and tan on it. I tried using Pythagorean formula on getting the hypotenuse first but still I can't seem to figure this one out since it may be on the lack of given values or probably I'm missing something.
Your guides would indeed help me a lot on this one!!! Thank you very much!!!
