### Example Question #1 : Understanding Arcsine, Arccosine, And Arctangent

What is if and ?

**Possible Answers:**

**Correct answer:**

In order to find we need to utilize the given information in the problem. We are given the opposite and adjacent sides. We can then, by definition, find the of and its measure in degrees by utilizing the function.

Now to find the measure of the angle using the function.

If you calculated the angle's measure to be then your calculator was set to radians and needs to be set on degrees.
