Which expression finds the length of side x in this right triangle?

The expression which is used to find the length of the side x in the right triangle is:

We know that in a right angled triangle the Pythagorean Theorem holds true.

Pythagorean Theorem--

It states that if c is the hypotenuse of the right angled triangle and a and b are two legs  of the triangle then the following relation holds true:

Here we have:

Hence, we get by the Pythagorean Theorem that:

But since length can't be negative hence we have:

answer: i don't understand. what are the options

step-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
