    We can solve the length of u using Laws of Cosine since we are given with lengths of two side and one angle.

    The solution is shown below:

    cos U = (s²+t²-u²) / 2st

    cos 37° = (9²+15²-u²) / 2*9*15

    0.79863*270=306-u²

    u²=306-215.63

    u=9.5 units

    Therefore, the length of u is 9.5cm.
