Question

What is the length of AA' ?

Answer 1

Im Not Sure Of The 1st Step Or What To Do

Answer 2

If I am understanding the question correctly. You need the length from point A to point A'?
In that case you can make a right triangle

And we can use the Pythagorean theorem to solve for the length.
\[a^2+b^2=c^2 \rightarrow c=\sqrt{2^2+5^2}=\sqrt{29}\]
