Answer:
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
The answer is 77. if you do it the opposite way and multiply
