2 rational numbers are C. 2.777 and D. -7/3

a rational number is any number that can be expressed as the quotient or fraction p/q of two integers

as you know 0.7777 (7 repeat) = 7/9
so 2.777(7 repeat) = 2 7/9

<h3>Answer: 1080</h3>

====================================================

Explanation:

We have an octagon because there are n = 8 sides. The diagram below shows one way to number the sides so you can count them efficiently (without missing any or double counting any).

----------------

Plug n = 8 into the formula below

S = 180(n-2)

S = 180(8-2)

S = 180(6)

S = 1080

The 8 interior angles add up to 1080 degrees.
