Ax + by = C Is that what you need?
Answer: 42.5ft
Step-by-step explanation: The wording in your question is a little unclear. I assume that you are looking for how far the anchor line is from the base of the tower.
If so, you can use the Pythagorean Theorem.
a^2 + b^ = c^2
96^ + b^2 = 105^2
Solve for b, gives you about 42.53ft round up and it is 42.5 ft :)

Answer:

EQUATION OF LINE PERPENDICULAR



EQUATION OF LINE PARALLEL


380 - 18% of 380
= 380 - (18/100)×380
= 380 - 68.4
= 311.6
