Answer:
<h2>18</h2>
Step-by-step explanation:
The formula of a distance between two points:

We have the points (5, -7) and (5, 11). Substitute:

1.) y= 2/3x
2.)y= -1x + 1
3.)y= 2x + 1
4.)y= -2/3x + 1
The structure of the formula is y = mx + b.
m is the slope.
slope is found by rise over run.
b is the y intercept.
which is found by where the line is on the y axis
90 = right angle
Any angle bigger than 90 is obtuse and any angle smaller than 90 is acute
