Your answer would be 7.94 units.
First we must note that a perpendicular bisector halves the side it is bisecting, so FA = FB. This then allows us to say that FA = 9, as 18 ÷ 2 = 9.
Now that we know FA = 90, we can see the right triangle with a hypotenuse AD, which is 12, and a leg FA, which is 9.
This then allows us to use Pythagoras's Theorem to find a leg of a right triangle, c² - b² = a², so we can do:
12² - 9² = 144 - 81 = 63
√63 = 7.93725, which is 7.94 to the nearest hundredth.
I hope this helps!
Step-by-step explanation:
In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. Multiply the top equation by 5. Now multiply the bottom equation by −3. Next add the equations, and solve for y.

Display and label your new polynomial identities. Identify each step and demonstrate that your identity works in numerical relationships
A+b+c=56
a=√625=25
b=2√81 = 2x9=18
c = 56-25-18=13
80/130 simplified would just be 8/13, and that is the simplest form.
Final answer: 8/13
Hope this helped! :)
