A lamppost, CAB, bent at point A after a storm. The tip of the lamppost touched the ground at point C, as shown below: Triangle ABC has measure of angle C equal to 60 degrees, measure of angle ABC equal to 90 degrees, and length of BC equal to 14 feet. What is the height, in feet, of the portion AB of the lamppost?

I understand i have to use soh cah toa, but i only get one calculation here, and thats the adjacent

14 divided by cos 60 degrees 14 tan 60° 14 divided by tan 60 degrees 14 cos 60° these are the options im given.

you have enough information to figure out the answer. You have the measure of angle C so use that to your advantage.
anonymous
  • anonymous
in relation to angle C you know the adjacent side and you want to know the opposite side. Which trig function relations opposite and adjacent sides?
anonymous
  • anonymous
the tangent function
anonymous
  • anonymous
so would it be 14 tan 60?
anonymous
  • anonymous
perfect, so plug in what you know...you know the angle is 60, you know the adjacent side is 14
anonymous
  • anonymous
solve for what you don't know (opposite side)
anonymous
  • anonymous
oops, I just saw your answer. Yes, 14 tan 60
