Okay, so all you need to do is to find the missing angle.
First, remember that all the angles of a triangle equal 180°. So if you know two of the angles, all you have to do is add them, then subtract the sum from 180.
1. 78 + 37 = 115 180 - 115 = 65 Do the same thing for each triangle and your answers are.
1. 65° 2. 34° 3. 67° 4. 58°
Answer:
f(x) = 417(3.15) x the second option which is the only one with correct units from the question
Lets say, for ease, that the vat can hold a total of 70 gallons (or whatever you would like to use.) Use whatever number you want, I just picked this because it gives us a lot of clean numbers.
Now, if the inlet can fill it in 7 hours, that means that it is adding 10 gallons per hour. (70 gal/7 hours = 10 gal/hr)
For the outlet, use the same process, and you find that it drains the vat at 7 gallons per hour.
So, if you subtract the outlet from the inlet, you get 10 - 7 = 3 gallons per hour added.
Now just divide the size of the vat by that number, and you find your answer.
70 gallons / 3 gallons per hour = 23 1/3 hours.
