26) are 33° and 52°, respectively. Find the distance from the balloon to the point closest to it if the distance between the points is 20 meters. Assume the balloon is positioned between A and B directly over a straight line that joins A and B. The angles of elevation to a balloon from two points A and B on level ground 27) are 26° and 46°, respectively. Find the distance from the balloon to the point closest to it if the distance between the points is 1.75 miles. Assume the balloon is positioned not between A and B directly over a straight line that goes thru A and B. The angles of elevation to a balloon from two points A and B on level ground 28) moving straight toward him. If the angle of depression to the 18-wheeler changes from 15° to 30° during the period of observation, how far does the semi travel? From the rooftop of 500-foot tall skyscraper, a man observes an 18-wheeler 29) tower. If the observer walks 200 feet further away from the tower and measures a 6° angle of elevation to the top of a transmission tower, about how tall is the tower?
