10.
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..
