Don't add.

There is a different problem:

The sine is not the right trigonometric function...
The right function will give a similar, but not the same result.

Yes (Good catch mfb.) But you need all three items in the answer: the direction, the numerical magnitude and the units. If you omit any of those it could be marked wrong.
