Question

Use a calculator to find the approximate angle measure of the following : cos^-1 (1/4)

Answer 1

Answer:

$75.52^o$

Step-by-step explanation:

Let

x ----> the measure of the angle

we have

$cos(x)=\frac{1}{4}$

using a calculator

Find the the measure of angle x

$x=cos^{-1}(\frac{1}{4})$

$x=75.52^o$
