A 96-ft high transmission tower casts a 72-ft long shadow. An anchor wire runs from the top of the tower to the tip of the shado
w. A ladder is set up vertically 66 feet from the base of the tower so the top of the ladder touches the wire. What is the height of the ladder? A. 6ft
B. 8ft
C. 10ft
D. 12ft
See attached picture and check solution below. We are given with the following values: A = length of transmission line = 96ft B = length of shadow = 72 feet C = distance of ladder to base of transmission line = 66 feet
Solve for angle created between the wire and tip of the shadow: tan x = opposite/ adjacent tan x = 96 feet / 72 feet x = 53.13°
Solving for the height of the ladder: tan x = Ladder length / (72-66) tan 53.13° * (72-66) = ladder length ladder length = 8 feet
Because had 8 but bought 9 more to where he then had 17 but if you take 8 times 2 then your answer is 16 and that's how many comic books he began with.
