    You need to show your work. What are you having problem with? These seem like straightforward questions.

    Doesn't your textbook provide an example of a similar or related problem? You have two variables in your equation. If you know one of them, how can you determine the other?

    The first part is simple maths.Use your quadratic formula knowledge to the maximum.
    The next part is simple trigonometry.Use tan theta to feel comfortable. ;p
    Show some work.A man without his own work, even though he may be genius, is a superstar without films at hand.
