By the geometric mean theorem,

\frac{y}{4}=\frac{12}{y} \\ \\ y^{2}=48 \\ \\ \boxed{y=4\sqrt{3}}

So, by the Pythagorean theorem,

12^{2}+(4\sqrt{3})^{2}=x^{2}\\\\144+48=x^{2}\\\\192=x^{2}\\\\\boxed{x=8\sqrt{3}}

p

q

. An irrational Number is a number on the Real number line that cannot be written as the ratio of two integers. They cannot be expressed as terminating or repeating decimals. For example.

Pi = 3.14…..It continues forever and never repeats. The few digits of  this pattern look like 3.1415926535897932384626433832795

√3 = 1.732050807. So one of the most important thing about irrational numbers is that it never repeats and never terminates.
