I like how this is set up because now i'm seeing that irrational denominators are fine.
00:08
And what you can also, i guess, visualize from this problem is you have theta is over here, side length of three, side length of five, and you can utilize the pythagorean theorem, what's called the c.
00:24
So leg squared plus leg squared has to equal the hypotenuse squared.
00:29
And even if you mess up, you can see that it might make sense with your answer options where they get the square root of 34 then on this, because that's how you would solve for c's.
00:44
So this side length is 34.
00:47
So you heard me say that the side length that's across in the right angle is the hypotenuse, across from the angle is what we call the opposite side.
00:57
And that leaves with adjacent.
01:00
And i use that as a pretty universal, so catoa, where sign of that angle, that's what the s stands for, is equal to opposite over hypotenuse.
01:12
So opposite is three, hypotenuse is root 34.
01:17
The next one that they ask for, actually they ask for tangent first, which is actually really nice that they ask their tangent first, because it kind of tells you right away, that tangent is opposite over adjacent.
01:31
Well, opposite is three.
01:33
Jason is five.
01:34
So slide that over.
01:36
The next one that they asked for is co -secant...
