Answer:
Im not completely sure, but here is my thinking to help you.
Explanation:
So we know the interior angles are 60, 30, 90. 19 times the square root of 3 is a very large number. (32.908...)
I think you can use the interior angles to find the value of y, then use the Pythagorean theorem to find the value of x.
Im not sure how to do this, but this is just my thinking.
