Hello all
I need help with the following question
Two ships A and B are sailing away from the point O along routes such that angle AOB = 120 degrees. How fast is the distance between them changing if, at a certain instant OA = 8 mi. OB = 6 ,i., ship A is sailing at the rate of 20 mi/hr, and ship B at the rate of 30 mi/hr.
I drew an obtuse triangle with the angle 120 degrees. Then I tried using the law of cosines to find the sides. I want to find dY / dt.
Any help is greatly appreciated
Thanks
