    The above is my attempt to solve question a), is this right approach? Now all i need to do is solve for theta? Or am i completely off track?

    Also, i have no idea how to approach question b). some insight would be helpful... Thanks!

    Yes, you have the correct approach. Yes, now solve for θ.

    Solving (a) will help you see how to answer (b).

    Looks like you're on the right track. Google trigonometric identities to figure out how to solve the quadratic. You'll get two angles as a solution.
