a. Barbara is about to ski down a mountain in Oregon. She estimates the angle of depression from where she is now to the finish line of the course to be 22*. She knows that she is 400 feet higher than the base of the course. How long is the path that she will ski? (Round to the nearest foot).
b. Barbara forgot her skis at the top of the mountain so she needs to trek back up to retrieve them! From where she stands at the finish line, the angle of elevation to the top of the mountain is 22*4'. If the base of the mountain is 454 feet from Barbara, how high is the mountain (to the nearest foot) ?
