Answer: 10.2956
Step-by-step explanation:
Input Data :
Point 1 (
x
A
,
y
A
) = (7, -1)
Point 2 (
x
B
,
y
B
) = (-2, 4)
Objective :

Distance between points (7, -1) and (-2, 4) is 10.2956
We are already given with the following
BC = 4.5
CD = 7.7
AD = 16.7
We are asked for AB
Assuming that the line segments are colinear, we have the equation
AB + BC + CD = AD
Substituting
AB + 4.5 + 7.7 = 16.7
AB = 4.5
Answer:
104.77 per cd (why so expensive?)
Explanation:
733.43 ÷ 7 = 104.77
