Question

Angelina says that she can find the exact length of only one side of the pentagon below.

What is the length of the side that Angelina can find?
3 units
4 units
6 units
8 units

Answer 1

8 units because...

Explanation:

At the bottom is the only side that can be determined and if you count the units it is 4 but be careful it's counting by 2s so you have to double the 4 to 8 so 8 is your answer plus i took the test.√

Answer 2

8 units

Explanation:

In the figure we have a pentagon with the following vertix: (2,6), (8,2), (6,-6), (-2,6), (-4,2).

Using analytic geometry we could find the distance between any two points of the pentagon. However, by looking at the picture we can also find the length of one side.

We observe that the side on the bottom has one extreme in (-2,-6) and the other one in (6,-6)

This particular side is a straight line parallel to the x-axis, therefore by simple inspection we can see that the length of the side is the distance between -2 and 6 (the abscissa of those points)

The distance between -2 and 6 equals 8.

Therefore, this side has a length of 8 units.
