So:
Answer:
x = 120
Step-by-step explanation:
First you want to get the equation into the form cosx = a
2 cos=1
Divide both sides by two to get it into the form.
cos=
Now, on your calculator, use the inverse of cos, to solve for .
=
(
)
= 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.
