Kirk vists Yellowstone Park and Old Faithful on a perfect day. His eyes are 6ft from the ground, and the geyser can reach heights ranging from 90 feet to 184 feet.
In the afternoon, Kirk returns and observes the geyser's spray reach a height of 123 feet when the angle of elevation is 37 degrees. How far from the geyser is Kirk standing to the nearest tenth of a foot?
The answer is suppose to be 155.3, could someone please help me? I COS, TAN, and SIN but I did not find the right answer.
