Answer:
<h2>The slope is undefined</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are (-11, -19) & (-11, -10)
The slope is
Any number divided by zero is undefined so the slope of the line here is undefined.

The value of x is 5 by using external angle
<u>P = 2L + 2W</u>
Subtract 2L from each side: P - 2L = 2W
Divide each side by 2 : <em>(P - 2L) / 2 = W </em>
