    ok. This type of triangle with the 90degrees and the 45degrees is a special type of triangle. Isosceles, i think. This means that the 7 side and the y side are always equal. the 45degrees and the unlabeled angle are the same, because the angles of the triangle add to 180. so, 180 - 90 -45 = 45. the unknown angle is 45degrees. Which also proves that the sides, 7 and y are the same length. Then to find x, you can use Pathagorean's theorem. (spelling?) ... which says \[C^2 = A^2 + B^2\] where C is the hypotenuse (across from the right angle), and A and B are the other sides. So, for your problem, \[x^2 = 7^2 +7^2 = 49+49=98\] \[x = \sqrt{98}\]
