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
