And here is Derek's take on Art Tatum's take on Tiger Rag.

DP Tiger Rag.

I'll tell you.

It's a joint of tubes.

Naturalism. Detail.

And she wrote a little note, she said,

Let me draw it a little bit neater than that.

And it deals with right triangles.

And since that is a triangle that has a 90 degree angle, it's a right triangle.

I wanted to introduce you to are acute angles, right angles, and obtuse angles.

Now what else can we figure out?

And so if this angle right over here is 4x, it has a corresponding angle where the transversal intersects the other parallel line.

So let me draw it in the same yellow.

Take a look at this.

So let me draw some right triangles, let me just draw one right triangle.

Cubic chickens and cubic eggs.

Энд байгаа налсан 2 өнцгүүдийн нийлбэртэй тэнцүү.

So it's D.

Let me draw my right triangle just like that.

How do I know it's not 15 or 16?

A very fancy word for a very simple idea.

I could also so the acute angle could be this angle right over here.

They're the same measure and they're supplementary

Do I do it upside down?

Now, both of these triangles are also isosceles triangles, so their base angles are going to be the same. So that's one base angle, that's the other base angle.

We know that this is going to be equal to it's vertical angle.
