Answer:
14.77 feet
Step-by-step explanation:
Using the pythagoras theorem to get the length of the ramp
l² = 13² + 7²
l is the length of the ramp
l² = 169 + 49
l² = 218
l = √218
l = 14.77 feet
Hence the length of the ram is 14.77 feet
SOLUTION:
Step 1:
In this question, we are given the following:
What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?
A. (-3.5, 1)
B. (1.5,-4)
C. (-4,1.5)
D. (1.-3.5)
Step 2:
The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

The first one (18) is the answer
Y=mx+b
m=slope
perpendicular lines have slopes that multiply to get -1
the slopes are
for

and

, the slope are

since their product is -1, the lines are perpendicular
