1. A Tree trimmer has a ladder 4 meters long. It is leaning against a palm tree at a 70 degree angle with the ground. How far up the tree does the ladder reach?
-
the ladder (4m) is the hypotenuse.
the vertical distance up the tree that the ladder reaches is the side opposite the angle.
so the vertical distance, or height, is equal to
4 sin (70) = 3.76 m, approximately.
