<h2>Explanation:</h2><h2 />I have corrected your diagram so ∅ is the angle at the top of the diagram. In order to solve this problem we have to use Pythagorean theorem and the law of sines. Moreover, I have named two sides as w and z so those variables will help us to solve this problem. So:
The triangle at the bottom is right, so by Pythagorean theorem is true that:
By law of sines:
By law of sines again:

The 'i' should go in front of the square root, not inside it.
So the answer should be
--------------
The way they wrote the expression is bit misleading as it might imply that the 'i' is under the square root. However the square root ends after the "5". It might be better to say
so there is clearer separation. But sticking the "i" in front is also a valid option.
side note: the plus minus part is already handled so there's no need to worry about that.
