I have a right triangle, and i have a side of x opposite angle a.
00:08
My hypotenuse is z, so b and b.
00:18
I'm sorry, that's y.
00:19
Opposite a we're going to call x.
00:23
Okay, and i'm told the sign of b is 1 over radical 3, and x is 4.
00:33
I want to find the length of the other side y.
00:37
Okay, so i'm just going to make a separate triangle, and i'm going to label them the same way, a and b.
00:43
So if i have the sign of b, then i know that side opposite b is one, and the hypotenuse is rad 3.
00:51
I'm going to use pythagorean theorem to find that missing third side, which is a leg of the triangle...
