    I take it this is maths homework - well you will want to use the cosine or sine rule, can't think which without a diagram in front of me.

    Homework is to do yourself at home - that's the point :)

    Law of sines will work, but this problem is just getting at a basic understanding of what a sine is. Remember, the definition of the sine is length of opposite side over length of adjacent (you need to memorize that!) So for this problem sin(30) = 1/hypotenuse.

    For the remaining angle: remember that the sum of angles in a triangle always add up to 180 degrees. You already know values for 2 of the 3 angles; use simple subtraction to find the 3rd.
