and
respectively.
Step-by-step explanation:
The given trigonometric equation is
We divide both sides by to get,
This implies that,
We take the inverse tangent of both sides to get,
Since the tangent ratio has a period of , another solution is
to the nearest degree.
In the third quadrant,
The solutions are
The value of x that satisfies the equation if x lies in the second quadrant is
The value of x that satisfies the equation if x lies in the third quadrant is
