angles are 90, 71.35651 and 18.643 degrees. The right trangle is part of a trapezoid that has a lower base with a length of 10.43cm, so the side of the right trangle adjacent to the 71.35651 degree angle could have a length of (10.43 - x) if x represents the side of the rectangle that would result if the right triangle were removed from the trapezoid. Any ideas?

It would require at least one more piece of information. It could be something apparently unrelated (the area of the trapezoid for example), but the given information is not enough by itself.

You can't find the side lengths if no side lengths are known.
In terms of x, the hypotenuse is (10.43 - x) / cos 71.35651° and the opposite side is (10.43 - x) tan 71.35651°.
I would suggest that you need to look at the other information in the problem to determine x and hence the side lengths.

If you call y the other side, adjacent to 18.643 you can write:
tan71.35651 = y/(10,43 -x) and
tan18.643 = (10,43-x)/y
That is a system of two equation on x and y.
Solving the system you obtain x and y ... and 10,43 -x
the two sides.

You gotta use the sin or cos function.
