<span>Hey there, Lets solve this problem together.
You are given two lengths of a right angled triangle, so Pythagoras' theorem is the way to go.
</span>In algebraic terms, a² + b² = c² where c is the hypotenuse while a and b<span> are the legs of the triangle.
</span>
In a right angled triangle:
the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
c² (the diagonal squared) = a² (one length squared) + b²<span> (the other length squared)
</span><span>leg a and b are both 3
</span>
<span>The opposite of ^2 is ^1/2 also known as the square root
</span>
<span>c = sqrt(18)</span>
Solved = <span>c≈4.24
