A . ` x = (d tan beta)/(tan alpha + tan beta) ; Y = (d tan alpha tan beta)/(tan alpha + tan beta)`

B . ` x = (d tan beta)/(tan alpha - tan beta) ; Y = (d tan alpha tan beta)/(tan alpha - tan beta)`

C . ` x = (d tan alpha tan beta )/(tan alpha + tan beta) ; Y = (d tan beta )/(tan alpha + tan beta)`

D . none of the above.
