Recall that for a polygon to have 180° as the sum of its interior angles, then it must have three sides and thus a triangle. And similarly, for a polygon to have a sum of 360°, it must have four sides or it is a quadrilateral.
[Note that for larger angles, we can apply the formula 180(n - 2) to find the total sum of the interior angles. n is the number of sides]
Now, since we're comparing a four-sided and three-sided polygon, this means that they only differ by 1 side.
Answer: A. 1 side
Answer: -5/2
Explanation: Rise over Run. Since the line is going downwards, the slope is negative
First subtract 3 from 51 which gives you 48, then divide 48 by 3 which gives you the answer of 16.
