WX = 8 mm

Step-by-step explanation:

To be able to solve for WX, we need to first find the size of angle .

We use the law of sines in the blue triangle to do such:

Now we can use this value in the larger right angle triangle where WX is the opposite side to angle  , and the 20 mm side is the hypotenuse:

which rounded to the nearest integer gives

WX = 8 mm
