We will see that the solution in the given interval is: x = 0.349 radians.
<h3>How to solve equations with the variable in the argument of a cosine?</h3>
We want to solve:
cos(3*x) = 1/2
Here we must use the inverse cosine function, Acos(x). Remember that:
cos(Acos(x)) = Acos(cos(x)) = x.
If we apply that in both sides, we get:
Acos( cos(3x) ) = Acos(1/2)
3*x = Acos(1/2)
x = Acos(1/2)/3 = 0.349
So x is equal to 0.349 radians, which belongs to the given interval.

Hello!
The equation for point-slope form is
y - b = m(x - a)
m is the slope
(a, b) is a point the line passes through
We are looking for a equation that follows this
The answer is C because a point the line goes through is (6, 2)
The answer is C
Hope this helps!
