This is only part of a possible path to getting the desired result of finding XY.
Drawing the figure, Pythagorean Theorem gives EY as .
Measure of angle XYZ is 90 degrees, a Right Angle.
Use sine of angle EYZ, or use to find measure value of this angle.
Angle Measure XYZ, , which was just found EYZ.
Now you can find angle measure at X.
Now angleas at X, at Y, at E (of the upper triangle) are known, and EY or YE was found earlier. Law of Sines for finding XY.
