Trig :D
theta = arctan (5/11) = 24.44 degrees
i dont understand what the top 5 ft in the diagram refers to
i think itsheight from the base of the triangle to the tip look at the really small arrows on the right side of the pic
oh - i see so height of middle triangle is 10 ft so sin 24.44 = 10/ c so c = 10 / sin 24.44 = 24.17 ft tan 24,44 = d / (24.17/2) so d = tan24.44 * 12.085 = 5.49 ft
so for number 16 its 24.17?
you can calculate g using pythagoras = sqrt(10^2 + 11^2) = 14.87 ft
its wrong, its not 14.87 :/
