Question

Based on the given triangle, the cosine of the 30 degree angle is:

Answer 1

Answer:

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

Step-by-step explanation:

Remember SOHCAHTOA

The cosine of an angle in a right triangle is the adjacent sides length divided by the hypotenuses length

In this case, for the angle 30 degrees, the adjacent length is $\sqrt{3}$ and the hypotenuse's length is 2

So, the cosine of the 30 degree angle is the first option:

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