"A plane flying with a constant speed of 19km/min passes over a ground radar station at an altitude of 10km and climbs at an angle of 20 degrees. At what rate is the distance from the plane to the radar station increasing 2 minutes later?"
So I drew up a triangle with a vertical height 10km and an angle of elevation of 20 degrees. But I'm not sure how to proceed after this. What equation do I have to set up so that I can implicitly differentiate it? How would I relate the triangle into it?
Any help?
