I'm assuming you want to find the hypotenuse right?

So we basically have this triangle set up:

Since we can see that the triangle has legs of 5 and 2 with a hypotenuse of x, we can use Pythagoreans theorem to find the unknown side.

Pythagoreans theorem:

where a and b are the legs of the triangle and c is the hypotenuse

Plug in a=5, b=2, and c=x. Now lets solve for x

Square each individual term

Combine like terms

Take the square root of both sides

Which approximates to...

So our answer is

which means

5^2+2^2=c^2 or 25+4=c^2 or 29=c^2 or c=sqrt29 or c=5.385 answer.
