Like Denise said, there's no actual problem listed here...
BUT
some general principles to review.
Draw a right triangle in which angle u is one of the angles other than the 90-degree one.
Remember SOH CAH TOA...
The sine is Opposite over Hypotenuse.
In other words, look at the length of the side Opposite to angle u, the side that doesn't actually touch it.
Then divide it by the length of the hypotenuse, the longest side of the right triangle (the one opposite the right angle).
That's the sine of angle u!
