Answer 1

The first answer is 4/3 I took the test

Explanation:

Answer 2

The first one is 4/3

We can solve by,


`{x}^(2) * 180 = 320`


`x = (4)/(3)`


`{ (4)/(3) }^(2) * 180 = 320 = true`

~~

The second one is 35.

Idk how to explain...

~~

The third one is a 6 - gon therefore cannot be C or D.

I'd say the third one is A., it looks like it's caving in.
