Answer:
44.1
Step-by-step explanation:
Cosine = Adjacent over Hypotenuse
Adjacent of ∠T = 28 and hypotenuse = 39
Which means that 
Now we solve for x
To get rid of the "cos" we take the inverse of cos ( which is
) and apply it to each side

We're left with x = 44.11461855
Our last step is to round to the nearest tenth and we get that the answer is 44.1
C. 4,990. Because it's the closest
Answer is B. 25 per half hour so 50 per hour, therfore 50 x 3 hours = 150
