I am having trouble understanding this concept, I would appreciate it if you could help explain this problem.

The problem uses a right triangle with BC=2 and the angle phata=45, I need to find any missing angles or sides, with the answer to at least 3 decimal digits.

AB=

AC=

B= This is not "B" but the angle of the letter that looks like B but it has a little line that extends below B.

I hope this is enough information, I looked at my notes and it still is not sinking in.

Thank you very much!!!!!!
