Answer:
17.54 ft
Step-by-step explanation:
Moving along the line from (–4.2, –6.4, 4.5) to (7.1, 2.2, 5.8), x increases by 11.3, y by 8.6 and z by 10.3.
Applying the Pythagorean Theorem twice, we get
(length of clothesline) = √( 11.3² + 8.6² + 10.3²), or 17.54 ft.
Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is 
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20
