Question

Find each angle measure to the nearest degree.
15) tan C = 0.1405

Answer 1

`C=8^o`

Explanation:

To find the angle C given the equation
`tan(C)=0.1405`, use the "arctan" function [which is the inverse function of tangent] on both sides of the equation as shown below:

`tan(C)=0.1405\\arctan(tan(C)) = arctan(0.1405)\\C=arctan(0.1405)\\C=7.9977^o`

This can be rounded to the nearest degree as:
`C=8^o`
