Answer 1

Wow, it's take some work! You also need to use Pythagorean theorem a lot.

Answer 2

a First, find x². There is two different way to find x².
AND

Now set equations to be equal to each other.
\[x^2 = (a + 5)^2 + 12^2 = (a + 23)^2 + \left(\sqrt{12^2 + 18^2}\right)^2\]\[\boxed {(a + 5)^2 + 12^2 = (a + 23)^2 + \left(\sqrt{12^2 + 18^2}\right)^2}\]
Is this clear? Can you find a from here? Sorry if it looks complicated.

Answer 3

Fixed.
