A woman wishing to know the height of a mountain measures the angle of elevation of the mountaintop as 12.0. After walking 1.00 km closer to the mountain on level ground, she finds the angle to be 14.0. (a) Draw a picture of the problem, neglecting the height of the womans eyes above the ground. Hint: Use two triangles. (b) Using the symbol y to represent the mountain height and the symbol x to represent the womans original distance from the mountain, label the picture. (c) Using the labeled picture, write two trigonometric equations relating the two selected variables. (d) Find the height y.

A high fountain of water is located at the center of a circular pool as shown in figure below. Not wishing to get his feet wet, a student walks around the pool and measures its circumference to be 12.0 m. Next, the student stands at the edge of the pool and uses a protractor to gauge the angle of elevation at the bottom of the fountain to be 55.0°. How high is the fountain? 55.0°
A statue 4.23 meters high is standing on a base of 4.90 meters high. If an observer's eye is 1.93 meters above the ground, how far should he stand from the base so the angle subtended by the statue is maximum?
Two fire wardens are stationed at locations P and Q, which are 45.0 km apart. Each warden sights the forest fire at F. Given that angle FPQ is 52.0 degrees and angle FQP is 43.0 degrees, find the distance from F to the nearer warden, to the nearest 0.1 km.
EXERCISE HINTS: GETTING STARTED I I'M STUCK! While standing atop a building 46.4 m tall, you spot a friend standing on a street corner. Using a protractor and a dangling plumb bob, you find that the angle between the horizontal and the direction to the spot on the sidewalk where your friend is standing is 23.2°. Your eyes are located 1.79 m above the top of the building. How far away from the foot of the building is your friend? X
When a man stands near the edge of an empty drainage ditch of depth 2.80 m, he can barely see the boundary between the opposite wall and bottom of the ditch as in Figure (a) shown below. The distance from his eyes to the ground is h = 1.88 m. (Assume ? = 33.0°.) Figure a. A man of height h stands a horizontal distance d left of an empty rectangular drainage ditch of depth 2.80 m. A ray starts at the bottom right corner of the ditch, extends up and to the left to the upper left corner of the ditch, and then reaches the man's eyes. The ray forms an angle ? with the vertical. Figure b. A man of height h stands a horizontal distance xleft of a rectangular drainage ditch that is filled with water. A ray starts at the bottom right corner of the ditch and extends up and to the left to the upper left corner of the ditch at an angle ? with the vertical. Upon exiting the water, the ray bends to become less steep than the ray in water, and extends up and to the left to the man's eyes. (a) What is…
