Answer:

Step-by-step explanation:

These problems are based on triangle ratios. You cannot use the Pythagorean theorem to solve them.

The first triangle is a 45 45 90 degree triangle (I'm talking about the angles), and so, the ratio is 1:1:\sqrt{2\\}, so I have to divide the hypotenuse by \sqrt{2\\} to get the legs. The hypotenuse is 15\sqrt{6}, so that divided by \sqrt{2\\} is 15\sqrt{3\\}. X is the same length as y because of the triangle ratio, so both x and y for the first triangle are 15\sqrt{3\\}.

The second triangle is a 30 60 90 degree triangle, so the ratio is x:x\sqrt{3}:2x. The short leg is 7\sqrt{3}, so 7\sqrt{3} * 2 is the hypotenuse, which is 14\sqrt{3}. The long leg is 7\sqrt{3} * \sqrt{3}, which is 21. So, x for the second triangle is 14\sqrt{3}, and y for the second triangle is 21.
