Homework Help: Trig

Posted by Trig on Thursday, September 10, 2009 at 5:29pm.

Two observers 1 km apart spot an airplane. The angles of elevation of the airplane from the two observers are 22 degrees 50 minutes and 24 degrees 40 minutes. If the observers and the airplane are in the some vertical plnae, compute the altitude of the airplane.

ok i don\'t know how to do this if you could show me how to do this

Also I think i may be reading this wrong i don\'t know

they put 22 then raise it to a circle which is used for degrees but than after that they do something like 50\' which i believe are minutes

a2 = unkown horizontal distance from observer to verticle component that the line of sight makes at the air plane

a2 tan 24.7 = opposite

(1 km + a2) tan 22.8 = x

a2 tan 24.7 = (1 km + a2) tan 22.8

not sure how to solve for a2
