Answer:
35
Step-by-step explanation:
Bobby is at negative 50 and his sister is above 15 feet (positive) so it is 35
I graphed it out and it seems that both A and C are correct. I would check them to make sure.
Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)
Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
