The answer is 5
Explanation:
We need to use the Pythagorean,
a^2 + b^2 = c^2
Where c is the hypotenuse
We can fill in spots now 12^2 + b^2 = 13^2
And then we solve 144 + b^2 = 169
Next we get b^2 alone
169-144=25
So we get b^2=25
For the final step you have to find the square root of 25 to get b alone which is 5
Rational number is something that does not have a decimal number going to infinity or something that can be written as a fraction
21.192 can be written as 21 192/1000 so yes its rational
i.e. √2 goes on forever and cannot be written as a fraction. so no it is not rational. it is irrational just like π.
