Step-by-step explanation:
According to the question a(n) = -5 for all real values of n.
So the 12th term in the sequence is -5.
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.
