Answer:

x = 6

y =
3√(2)

Explanation:

Thats a 45 45 90 triangle, one of my favorite and you'll come to miss it later because of how easy it is.

See the file provided for the trick

Because
3√(2) falls where a 1 is in the diagram that means y is also
3√(2) because you multiply
3√(2) by 1, and to get x you'll multiply the value we're given,
3√(2), by the value in the spot in the given diagram,
√(2).


3√(2) ×
√(2)

Note; a radical multiplied by itself is the value in the radical

Therefore,


3√(2) ×
√(2) = 3(2) = 6

Thus x = 6

The explanation for this;


√(2) *
√(2) =
√(2)^2

And if you square a square root you have its square root times its square root squared, which if it was
√(4)^2 it'd ultimately be
(2)^2 which is 2x2 which equals 4

Hope this helps
