Answer:
WX = 8 mm
Step-by-step explanation:
To be able to solve for WX, we need to first find the size of angle

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
