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.

40% of 50 is 20. So, 20/50 students who take the random sample prefer chocolate over vanilla ice cream. In order to find the number of students who prefer chocolate over vanilla ice cream out of 200 students in total, it is best to set up a proportion. Here: 20/50=x/200. Once you solve the proportion you will get x as 80.
Hope the explanation helped!
