5. diabeetus45

yes

6. diabeetus45

i want to know how to do it

7. mysesshou

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, $x^2 = 7^2 +7^2 = 49+49=98$ $x = \sqrt{98}$

18. diabeetus45

Hahaha, same for me! I had a question about math and I just finished talking to a friend about this guy who says "diabeetus" so i made that my name. haha. xD. & haha aww, that sucks :c

19. mysesshou

Ah well... all's good. Just spent a little bit too much time exercising the brain and not the body. I'm working on it though. Have a good night! good luck with your trig

20. diabeetus45
