    given: an angle, the legnth of the side opposite the given angle, and another length.. use sine law..

    \frac{\sin 75^o}{104.4} = \frac{\sin \theta}{98.4}, where \theta = \angle P

    11. given the two angle, you can find the third angle; use sine law again..
    12. same is true with here..
    13. use sine law..
    since angle U and u are given..
    14. same as 11
    15. same as 13..
