Christmath 2016: Find the Area (UPDATED)

(Click on the comic if you can't see the full image.)

This comic brought to you courtesy of The Law of Sines. Have a Happy Holiday. It's the Law.

I drew this on the white board and took a picture of it with the iPad in the classroom. I posted the original photo (with my title and (c) notice typed over it) on the blog early in the day, but I had to wait until I got home to clean up the photo a little. Funny thing was that I could lighten it up, but I couldn't auto-adjust the contrast -- too much junk from Whiteboard Past became suddenly visible!

The original photo is posted below.

Have a Merry Christmas, a Happy Holiday and Seasons Greetings to everyone out there.

Update: This came in email from longtime reader, friend and Scotch aficionado (which has nothing to do with this, just sayin'), Bill Ricker who wrote:

My favorite photo editor Fotoxx (only for Linux, best with Ubuntu) can do it too. IIRC it only rotates colors ... so Red->Green and Blue->Red instead of the Blue<->Green swap i did earlier.

So now we have a green tree with red lights, which fits the season a little better. Thanks, Bill!

Come back often for more funny math and geeky comics.

About 147.1 square feet, assuming the tree is conical and we're taking the "surface" to be a smooth, continuous plane across the tips of the branches, as suggested by your drawing.

Merry Christmas! :)

The wisdom of the Geometry is in the markings of the triangle and my unhallowed hands shall not disturb it. You will therefore permit me to repeat that it is a triangle, and an isosceles one, at that.

Our class reviewed The Law of Sines and finding an area using Sin (theta) this week, but no one chose to do the bonus problem, instead focusing on make-up work and gabbing.

Nice job

Merry Christmas to you as well!
