Another little problem that i cant see to get my head around.

Can anyone out there help me with it at all, any solutions would be great

here goes

"Two objects A and B are observed from two points C and D on level ground and 120m apart. The angles ACD, ADC, BDC, BCD are 108*, 32*, 87* and 43* degrees respectively"

What i need to know is the distance between points A and B

cheers guys
