So for the 40-40-90 degree triangle, whenever the two legs are x values, then the hypotenuse is x value times the square root of 2.

--> a changed into a√2
√2 changed in √2 * √2
= 2

So the hypotenuse of the 40-40-90 degree triangle is 2.

Now for the 30-60-90 degree triangle, the smallest leg with the value of x is then changed to the value of x√3 if finding the longer leg.

-> a is changed to a√3
2 is changed into 2√3

So, y is 2√3 or approximately 3.46 units.
