Answer:
[tex]\sqrt{128}[/tex]
Step-by-step explanation:
Right, let write down the Pythagorean Theorem equation or standard form of it. before we plug in the numbers.
[tex]a^2+b^2=c^2[/tex]
Right, so that is the equation of Pythagorean Theorem. So let plug in the numbers of b and c.
[tex]a^2+14^2+18^2[/tex]
So we have our values of b and c. Now, how do we find the missing number?
Well, let simplify thing further by squaring the numbers we have already.
[tex]a^2+196+324[/tex]
We will now subtract 196 from both side which gives us:
[tex]a^2=128[/tex]
Now we can square root the answer.
[tex]\sqrt{a^2} =\sqrt{128}[/tex]
Now, we are left with this:
[tex]a=\sqrt{128}[/tex]
So the final answer is [tex]\sqrt{128}[/tex] or the decimal value which is [11.31370849]
Round: 11.31
