    In a right triangle, the square of the hypotenuse equals the sum of the squares of the other two legs.

    |dw:1328570208471:dw| \[h=\sqrt{a^2+b^2}\] \[a=\sqrt{h^2-b^2}\] \[b=\sqrt{h^2-a^2}\]

    \[h^2=a^2+b^2\]

    where c represents the length of the hypotenuse, and a and b represent the lengths of the other two sides.

    In any right triangle, the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares whose sides are the two legs (the two sides that meet at a right angle).

    The square roots come in because the pythagorean theorem tells you the sum of the squares of the legs equal the square of the hypotenuse. You have to use the square root to find the number. \[(\sqrt{a^2})=a\]

    Here, you wouldn't use the pythagorean theorem until you use some trig to find one side.

    for example in this question we need to find c^2 by finding c^2 we plug in the formula a^2+b^2=c^2 6^2+7^2=c^2 36+48=c^2 \[\sqrt{36}\]+\[\sqrt{48}\]

    \[\tan(60º)=\frac{9\sqrt{3}}{x}\] \[x=\frac{9\sqrt{3}}{\tan(60º)}\]

    When you find x, now you can use the pythagorean theorem. \[y=\sqrt{x^2+(9\sqrt{3})^2}\]

    oh man my teacher never told me we had to use tan to solve this answer

    Well, this is a special right triangle, so I suppose you don't have to use trig. It is a 30-60-90 triangle, did your teacher tell you how to solve these?

    http://www.cliffsnotes.com/study_guide/Special-Right-Triangles.topicArticleId-18851,articleId-18821.html Look at this link, it tells you the relationship between sides in special right triangles so you don't have to use trig.
