A variation of the subtense bar method that surveyors use to determine larger distances d between two points P and Q is shown in the figure. In this case the subtense bar with length b is placed between the points P and Q so that the bar is centered on and perpendicular to the line of sight connecting P and Q. The angles & and ß are measured from points P and Q, respectively. Find a formula for d involving a, ß, and b and use this formula to determine d if x = 30' 45", B=35' 9", and b = 2.078 cm.
