If it helps the answer according to this ACT compass sample test questions print out is 6.93.
How to solve it is the question ...
C is a 90 degree angle.
AB is 8 and the hypotenuse.
AC is the base .... we don't know it's length.
It's on page 14 if you google this 
2014 ACT In the right triangle shown below, the length of AB is 8 units

recall your basic trig definitions, and draw a diagram. You will see that
BC/8 = sin 60°
BC/8 = 0.866
BC = 6.93
If this gave you difficulties, you have some serious reviewing ahead.

Dude,
throw me a bone ....? I'm try'n to learn.
I see that A sin 60 degrees is equal to BC/8 (8 = the hypotenuse).
C is a right angle.
BC is the height.
Wait. I think I see it now....?
Because Sin equals BC(opposite)/H(8)and we know that the result of this equals .866, we can multiply .866 x 8 which will give us 6.928?
