Answer:
C. R = 17.9 degrees
Step-by-step explanation:
We have a rectangle triangle with the adjacent side and the opposite side (neither of which are the hypotenuse).
The relation between those elements is the tangent:
![tan(angle) = \frac{Opposite side}{Adjacent side}](https://tex.z-dn.net/?f=tan%28angle%29%20%3D%20%5Cfrac%7BOpposite%20side%7D%7BAdjacent%20side%7D)
So, to isolate the angle, we modify the formula as such:
![angle = arctan(\frac{Opposite side}{Adjacent side}) = arctan(\frac{10}{31}) = arctan(0.3225) = 17.87](https://tex.z-dn.net/?f=angle%20%3D%20arctan%28%5Cfrac%7BOpposite%20side%7D%7BAdjacent%20side%7D%29%20%3D%20arctan%28%5Cfrac%7B10%7D%7B31%7D%29%20%3D%20arctan%280.3225%29%20%3D%2017.87)
If we round 17.87 degrees to the tenth... we get 17.9 degrees.

Answer:
80%
Step-by-step explanation:
Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%
Percentile = (8 / 10) * 100%
= 0.8 * 100%
= 80%
