What is the length of side x? if necessary, round your answer to two decimal places.

Because this is a right triangle, you can use the pythagorean theorem: a^2 + b^2 = c^2, where a and b are legs and c is the hypotenuse.

you have a leg, 18, and the hypotenuse, 26. plug those in:

18^2 + b^2 = 26^2 ... evaluate exponents
324 + b^2 = 676 ... subtract 324
b^2 = 352 ... square root both sides
b = √(352)
b = 18.76

Option C -

Step-by-step explanation:

Given : A system of equations has infinitely many solutions. If is one of the equations.

To find : Which could be the other equation?

Solution :

A system of equations has infinitely many solutions when the two lines representing the equations coincide.

i.e. the two equations are the same or a multiple of each other.

We have given the equation,

Taking 2 common from equation,

or

Take negative both side,

The other equation is  

Therefore, option C is correct.
