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

Step-by-step explanation:
Android calculator accepts the above question via copy and paste, and gives 0.5
The point of this question is to try to discover whether or not you know what the expression means.
Rewriting it as (8(15-4)/(4×4)) - 5 would show that you know the meaning. You can check that by feeding it into the calculator as well.
X^2 + 8x + 7= 0
(X+7)(X+1)
X=-1,-7
