The answer is Radical 6.
This is because if you use Cosine and the angle measured 30. You would put adjacent over hypotenuse, which is
Cos (30) = X/radical 8
Put this into your calculator to get Radical 6
32
the greatest common factor of 480 and 128 is 32
480 / 32 = 15
128 / 32 = 4
Original
Z = X/5
Solve for X
Multiply both sides by 5
5Z = X
Answer
X = 5Z
