Answer:
To solve the equation 4 cos x + 2 = 3 for x, you can begin by subtracting 2 from both sides of the equation to isolate the term with the cosine function:
4 cos x + 2 - 2 = 3 - 2
4 cos x = 1
Then, you can divide both sides of the equation by 4 to solve for x:
4 cos x / 4 = 1 / 4
cos x = 1/4
Since the cosine function has a range of -1 to 1, the only possible value of x that satisfies this equation is x = 30°.
However, you mentioned that you want to solve the equation for x = 0°. In this case, you would need to substitute 0° for x in the original equation and solve for the value of the other variable. For example, if the original equation was "4 cos x + y = 3," you would substitute 0 for x and solve for y:
4 cos 0 + y = 3
4 + y = 3
y = -1
This means that if x = 0°, then y = -1
