The sum of the measure of the exterior angles of any polygon is 360. x represents the measure of a single exterior angle.
360/56=x
The simplified fraction is 45/7

Answer: option (C)

Step-by-step explanation: The slope of a linear function is undetermined when the line is parallel respect to the y-axis. In the current problem there is no way to observe such geometrical issue, but if we consider how to derive the slope using the following expression; $m=\frac{\Delta y}{\Delta x}= \frac{y_{2}-y_{1}}{x_2-x_{1}}$ .

With the previous equation, we have

$a) for P_{1}(-1,1), P_{2}(1,-1) m=\frac{\Delta y}{\Delta x}= \frac{-1-1}{1-(1)}=\frac{-2}{2}=1\\$ , therefore the slope is defined

$b) for P_{1}(-2,2), P_{2}(2,2) m=\frac{\Delta y}{\Delta x}= \frac{2-2}{2-(2)}=\frac{0}{4}=0\\$ , therefore the slope is defined

$c) for P_{1}(-3,3), P_{2}(-3,3) m=\frac{\Delta y}{\Delta x}= \frac{3-(-3)}{-3-(-3)}=\frac{6}{0}=undetermined\\$

$d) for P_{1}(-4,4), P_{2}(4,4) m=\frac{\Delta y}{\Delta x}= \frac{4-(-4)}{4-(-4)}=\frac{8}{8}=1\\$

In this case, the option (C) shows that is not possible to divide over zero. Given such issue, the slope is undetermined and therefore it is a vertical line parallel to y-axis.

Find the value of X so that the rectangle and the triangle have the same perimeter. What is the perimeter?

kvasek [131]

Perimeter is the sum of all sides of a two-dimensional shape. Therefore, we can construct the following equation to find the value of X:

2x + 4 + 2x + 2 = x + 7 + x + 3 + x + 9
4x + 6 = 3x + 19
4x - 3x = 19 - 6
x = 13

If the perimeter of these shapes is the same, whatever which of them we use for calculating we will find the same result.

Rectangle:
13 + 2 + 13 + 2 + 13 + 1 + 13 + 1 = 58

Or

Triangle:
13 + 7 + 13 + 3 + 13 + 9 = 58

The perimeter is 58.
