We're asked to prove that triangle ADC is congruent to triangle BEC so this left triangle is congruent to this right triangle.
Well, if we look at this larger right triangle, that is the opposite of beta times its hypotenuse.
Given one side and one angle of a right triangle, it is possible to solve for all other sides or angles.
Now, this ratio, 5/12--I'm going to put it in parentheses to show that it's important-- every single time we see a 22.6 degree angle in a right triangle.
Well, we have a right triangle--we know something about the side opposite α-- that's the length of the shadow--and the side adjacent to α--that's the length of the bar.
Two right triangles.
So if you take two right triangles.
Everything we're dealing with, these are going to be right triangles.
Now we just have to get α, which will require trigonometry-- the study of triangles, specifically right triangles.
And then once I have right triangles, then now I can start to use trig functions and the Pythagorean theorem, et cetera, et cetera.
So if you're trying to find the trig functions of angles that aren't part of right triangles, we're going to see that we're going to have to construct right triangles, but let's just focus on the right triangles for now.
We're involving e, which we get from continuous compounding interest, we have cos(x) and sin(x), which are ratios of right triangles, it comes out of the unit circle, and somehow we have thrown in(-1)^(1/2), there seems to be this cool relationship here.
This is a right triangle.
It's a right triangle.
So this is a right triangle.
Let me draw a right triangle.
So this base of the right triangle is along the plane.
Let's figure out what's going on inside a right triangle.
Let's get some practice using these ratios. Here we have a right triangle.
If we look at this right triangle right here, is opposite over hypotenuse for alpha.
