I know that angle a=95 degrees, and side b=30 and side c=20

I also know that sinA/a=SinB/b=SinC/c

The sum of all angles in a triangle is 180. So if you know two of the angles of a non-right triangle, or if you know one of the non-90 degree angles of a right triangle, you can fingure out the remaining one by subtracting the two you do know from 180.

Drop a height in front of angle A to make two right angle triangles. Solve from there.

Use the law of cosines: a^2 = b^2 + c^2 -2bc cos A.
