Question

A wire is stretched from the top of a two feet tall anchor to the top of a 45 foot tall antena. If the wire is straight and has a slope of 3/5, then what is the length of the wire in feet?

Answer 1

I made a sketch on a grid, I labeled the point at the anchor (0,2) and the point of atachment at the pole as (x,45)
(45-2)/(x-0) = 3/5
3x = 215
x = 215/3

Now , use the formula for the distance between 2 points
