Answer:
62.77 million gallons
Step-by-step explanation:
Given,
The function that shows rate of leaking oil per minute in after t hours,

∵ 1 hour = 60 minutes ⇒ 3 hours = 180 minutes,
Hence, the quantity of oil leaked out in the first 3 hours,



![=0.7[tan^{-1}(t)]_{0}^{180}](https://tex.z-dn.net/?f=%3D0.7%5Btan%5E%7B-1%7D%28t%29%5D_%7B0%7D%5E%7B180%7D)


= 62.77 million gallons

10 quarts, because 2 x 2 = 4 quarts, then 1 gallon = 4 quarts, 4 + 4 = 8, then half of 4 is 2, which 8 + 2 = 10.
Ok, there are two scenarios here.
1) It's a typo and "<K" should be written as "<J"
if that is the case, we can convert from degrees,minutes,seconds >> degrees like so

once calculated, we get 48.43 degrees.
scenario 2)
<k is the third angle in a right triangle
this would mean that <j + <K + 90 = 180
from the first example, we know that <J = 48.43 degrees
Therefor
48.43 + <k + 90 = 180
48.43 + 90 = 138.43
so
138.43 + <k = 180
Therefor, <K = 41.57 degrees
I really hope this helps!!:)
