Answer:

x = 120

Step-by-step explanation:

First you want to get the equation into the form cosx = a

2 cos $\frac{x}{2}$ =1

Divide both sides by two to get it into the form.

cos $\frac{x}{2}$ = $\frac{1}{2}$

Now, on your calculator, use the inverse of cos, to solve for $\frac{x}{2}$ .

$\frac{x}{2}$ = $cos^{-1}$ ( $\frac{1}{2}$ )

$\frac{x}{2}$ = 60

Now you want to find x, so multiply both sides by 2.

x = 60 * 2 = 120

x can have many solutions; however, I have only given you one.
