The 45-45-90 triangle is an isosceles triangle, in which the sides would = 1, 1, √2, and 2√2 is the hypotenuse.
2√2/√2 = 2
So the sides missing are both 2.
now look at the 30-60-90 triangle. the sides would be 1, √3, 2. The "y" side is √3.
2 is in the place of the 1 side, and so your answer is 2√3, as 2 x √3 = 2√3
2√3 is your answer
hope this helps
