The answer is the 3rd option im pretty sure :)

Answer:
x = 17º
Step-by-step explanation:
We know that it's a right angle because of the smaller square where the vertices meet. We are given 73º. An equation you can use is
90 - 73 = x
x = 17
Secant and tangent theorem: Square of measure of tangent is equal to the product of length of whole secant and length of exterior secant segment, i.e.
.
The whole secant wuth exterior secant 4 cm is 4+x cm. Tangent is 7 cm. Using previous theorem, you can get that
.
Solve this equation:
cm.
Answer: x=8.3 cm.
The number of months overcharged for 1 gallon of leaky water = 1 1/3
= 4/3
Let us assume the quantity of water overcharged = w
Let us assume the time in months = t
Then, the equation modelling this direct variation is
w = (3/4)t
When w = 5, then
5 = (3/4) * t
20 = 3t
t = 20/3
= 6 2/3
From the above deduction, we can conclude that the first option or option "A" is the correct option. I hope the answer helps you.
