When the Good-Year Blimp is viewed from the field-level bleachers near the southern end-zone of a football stadium,
the4 angle of elevation is 62o. From the field-level bleachers near the northern end-zone, the angle of elevation is 70o.
Find the height of the blimp if the distance from the southern bleachers to the northern bleachers is 145 yards.

Approaching from the west, a group of hikers notes the angle of elevation to the summit of a steep mountain is 35o at a
distance of 1250 meters. Arriving at the base of the mountain, they estimate this side of the mountain has an average
slope of 48o. Find the slant height of the mountains west side (W). Find the slant height of the mountains east side
(E). If the east side has an average slope of 65o, how tall is the mountain?

Coffeyville and Liberal, Kansas, lie along the state’s southern border and are roughly 298 miles apart. Olathe, Kansas,
is very near the state’s eastern border at an angle of 23o with Liberal and 72o with Coffeyville (using the southern
border as one side of the angle). Compute the distances between these cities. What is the shortest distance (straight
line) from Olathe to the southern border of Kansas?
