Pythagorean Theorem Question

Answer: 10
Step-by-step explanation: Ok, so let's use the Pyhagorean Theorem of course.
a² + b² = c²
12² + b² = 16²
x + 144 = 246
246 - 144 = 102
b = 102
[tex]\sqrt{102}[/tex]
b = 10
I hope this is what you were looking for, have a good day!
[tex]\huge\boxed{10.6}[/tex]
This may not be too much, but here's my explanation...
[tex]\left[\begin{array}{ccc}16^2-12^2=B^2\\256-144=\sqrt{112}\\\sqrt{112}=10.583\\10.583=10.6. \end{array}\right][/tex]
Mods, if i am not doing this correctly and you see this just delete the answer i am new to pythagorean theorem.
