<PRE><B>Question 273868</B>
picture the taller pole standing at the origin and running up the y-axis


the shorter pole is standing 40 ft out on the x-axis


the equation of the wire from the top of the taller pole to the bottom of the shorter pole is ___ y = (-5/4)x + 50


the equation of the other wire is ___ y = (3/4)x


substituting ___ (3/4)x = (-5/4)x + 50 ___ x = 25


substituting ___ y = (3/4)25 = 75/4 = 18.75


C is 18.75 ft off the ground and 25 ft from the taller pole


leaving the third part for you to find
