Hello from MrBillDoesMath!
Answer:
Choice B, -2 sqrt(85) / 85
Discussion:
By definition,
cos(@) = length of side adjacent to angle / hypotenuse
= -2/ ( sqrt ( (-2)^2 + (9^2) ) (usin Pythag. theorem)
= -2/ sqty (4 + 81)
= -2 / (sqrt(85)
Multiply numerator and denominator by sqrt(85):
= (-2 / ( sqrt(85) ) * (sqrt(85)/sqrt(85) )
= -2 sqrt(85) / 85
which is choice B
Thank you,

Answer:
99 F
Step-by-step explanation:
"Three lower" means it was the original temperature - 3, so if the original temperature was 102, we have the equation:
102 - 3
99 F
so 99 F is the answer
It should be A if i am correct
