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

• Trig -

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.

• Trig -

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?
