Answer:
third side = 4
Step-by-step explanation:
third side is hypoenuse as it is opposite to 90 degree.
using pythagoras theorem
(perpendicular)^2 + (base)^2 = (hypotenuse)^2
2^2 + (2
)^2 = hypotenuse^2
4 + 4*3 = hypotenuse^2
16 = hypotenuse^2
= hypotenuse
4 = hypotensue
im sorry im just writing this so i can give you the answer but i think it is 135
Drops = 27
First, we need to find the volume of the given tank using the following equation

Now that we know the volume, we need to find out how many drops that we need to use. We can find that out using the following equation
