Hello. I am back with another trigonometry question. Any help with the following problem would be greatly appreciated.
A stepladder stands on a floor, with its feet 1.5 metres apart. If the angle formed by the legs is 55 degrees, how high above the floor is the top of the ladder?
I have tried dropping a perpendicular line from the top of the stepladder to the floor, and then applying various trigonometric ratios; this did not work. I have also tried putting the angle in different places. The best answer I could obtain was 1.46 metres; the real answer is 1.44 metres.
