Chapter 1, Problem 70AP
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 woman’s 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 woman’s 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.

During a visit to New York City, Lil decides to estimate the height of the Empire State Building (see figure below). She measures the angle ? of elevation of the spire atop the building as 19°. After walking x = 9.42 ✕ 102 ft closer to the iconic building, she finds the angle to be 24.0°. Use Lil's data to estimate the height h of the Empire State Building. (Enter your answer to at least the nearest foot.)
