Answer:
Either or .
Step-by-step explanation:
.
Hence, there are two possibilities to consider:
- Either ,
- Or .
If , then .
Substitute into the original equation: . Solve for : .
Important: verify that the solution meet the assumption . Indeed, and is indeed non-negative. Hence, the solution is valid.
On the other hand, if , then .
Substitute into the original equation: . Solve for : .
Similarly, verify that the solution satisfies the current assumption that . Indeed, this assumption is met, and is also a valid solution.

Pretty sure the answer is C - if not that then A
Use trigonometry to find L.
Tangent = opposite over adjacent on any right triangle.
tan(L) = 18/23
Take the inverse on both sides.
arctan(tan(L)) = arctan(18/23)
L = 38.0470425318
L = 38.05°
Done.
