Best ResponseYou've already chosen the best response.0it's trig so I am guessing a level plane which would mean it has a 90° angle at C.

Best ResponseYou've already chosen the best response.0Make a triangle out of the problem. Your horizontal leg is 144ft. Your vertical leg will be x because that is what you want to find. Your angle will be in between your horizontal leg and hypotenuse. Now it is time to pick a trig function that will answer your question... Tangent is opp/adj so it will incorporate what you need. Your equation is now tan23.5 = x/144. Now solve for x. .4348 = x/144 x is approximately 62.6
