The angles of elevation to a balloon from two points A and B on level ground 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.
