Once you divide a number up into prime factors, all of the number's factors are simply all combinations of these prime factors.

For example: the prime factors of 20 are 22 x 51 . The exponent 1 is normally not written;

Answer: $\frac{\sqrt{3}}{2}$

======================================================

Explanation:

The symbol $\theta$ is the greek letter theta. It's often used in trigonometry for angles.

In this case, $\theta = 30^{\circ}$

So,

$\cos(\theta) = \cos(30^{\circ}) = \frac{\sqrt{3}}{2}$

You'll need to use a reference sheet or the unit circle to determine the value of cos(30). Or you could use a 30-60-90 triangle template.

When using the unit circle, look in the upper right quadrant (which is quadrant 1). The angle 30 degrees is in this quadrant. Locate the terminal point and note how $\frac{\sqrt{3}}{2}$ is the x coordinate of the terminal point. This is due to $x = \cos(\theta)$

Side note: $\frac{\sqrt{3}}{2} \approx 0.866025$
