Answer:
The answer is choice B: 22.52 units.
Step-by-step explanation:
We use the Pythagoras's theorem which says for a right triangle with sides
and hypotenuse
:
![x^2+y^2=z^2.](https://tex.z-dn.net/?f=x%5E2%2By%5E2%3Dz%5E2.)
In our case
![z=26](https://tex.z-dn.net/?f=z%3D26)
![y=13](https://tex.z-dn.net/?f=y%3D13)
So we solve for ![x:](https://tex.z-dn.net/?f=x%3A)
![x=\sqrt{z^2-y^2}=\sqrt{26^2-13^2} =\boxed{22.52\: units.}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7Bz%5E2-y%5E2%7D%3D%5Csqrt%7B26%5E2-13%5E2%7D%20%20%3D%5Cboxed%7B22.52%5C%3A%20units.%7D)
Which is choice B.
Whatever you multiplied to the denominator, do it to the numerator.
