Question

What is the measure of 11 years ago

Answer 1

Hey Alli :)
Do you know the total size of the interior angles of a pentagon?

Answer 2

540

Answer 3

Mmmm ok good, that sounds right.
We can squeeze three triangles into a pentagon, so we have three 180's, which is 540.

Answer 4

\[\Large\rm 540=133+94+111+107+x\]These angles should add up to 540,
where x is our missing amount.

This shouldn't be too bad :)
Just figure out how much you're missing!
Add em all up, subtract from 540.

Answer 5

I figured it out. I choose 95. Thank you!
