Answer:
(D) 120 degrees
Step-by-step explanation:
From the figure drawn, we have
∠ABC=60°
And ∠OAB=∠OCB=90° (angles made by tangent on the circle is 90°)
Thus, ∠AOC+∠OCB∠CBA+∠OAB=360° (Angles sum property of quadrilateral)



Therefore, the value of x is 
Hence, option D is correct.
It will take 13 minutes and 30 seconds for the tanks to have an equal amount of water.
Since Louis is filling two tanks of water in his home, and Tank A currently contains 27 gallons and has a hose filling it at a rate of 3 gallons per minute, while the other tank, Tank B, has 38 gallons and is being filled at a rate of 2 gallons per minute, to determine how many minutes will it take for the tanks to have an equal amount of water, the following calculation must be made:
- 27/3 = 9
- 27/2 = 13.5
- 13.5 = 13 minutes 30 seconds
Therefore, it will take 13 minutes and 30 seconds for the tanks to have an equal amount of water.
