Have you learned how to use the Pythagoras theorem?

It states that, in a right-angled triangle, the sum of the squares of the two shorter sides add up to the square of the hypotenuse.

So, if the shorter sides are a and b long, then the hypotentise is h long where

h^2 = a^2 + b^2

For the first triangle, a = b = 3, so h^2 = 2*3^2 and h = 3sqrt(2)

For the second triangle, one side is 3sqrt(2) and the other is 3

so h = sqrt(3^2 + 2*3^2) = sqrt(3*3^2) = 3sqrt(3)

For the nth triangle h = sqrt((n+1)*3^2) = 3sqrt(n+1).......

So, start using what you've been taught already!
