If n = 44 mm and p = 67 mm, what is the measure of angle θ?
a. 41°
b. 57°
c. 49°
d. 33°

Option C

49°

Step-by-step explanation:

By definition, the cosine of an angle is defined as:

.

The hypotenuse is always the opposite side to the 90 ° angle

The adjacent side is the one that contains the angle theta and the angles of 90 °.

In this case note that:

So:

The answer is:

The correct option is:

C. 49°

To calculate the measure of the angle, we can use the following trigonometric relation:

We are given the following information:

So, substituting and calculating we have:

Hence, the correct option:

C. 49°
