I'm learning about trigonometric functions, and my worksheet instructs me to find the "missing information" for each triangle.
For the first one, they give me the length of the hypotenuse (45) and that theta = 35. How can I go about finding the missing info?

    sin35=Opposite/45 do this to find the opposite
    if it is a right triangle use a^2+b^2=c^2 to find the other side
    take 35+90-180 to find the other angle
    ONLY IF A RIGHT TRIANGLE

    Ok cool, I got that. Thanks a lot.

    However, this next one gives me the length of one leg (359) and the adjacent theta of 83. How exactly can I solve this?
