if AB is a BC is b find height in a and b in the given figure Share with your friends Share 0 Chirag Manchanda answered this Dear StudentLet the height =h and the distance from the right-angled vertex to point A =xThentanα =hx, x= htanαtan2α = hx +a = hhtanα+atan3α=hx+a+b = hhtanα+a +bThus, htanα+a =htan2αhtanα+a +b=htan3αhtan3α -htan2α =bh = b tan3α.tan2αtan2α-tan3αThis is an expression in form of b and αIf any other form is required or to be matched with the answer can further be reduced using known relations.In case you have a doubt with that please feel free to put it forth in a new thread.Regards 1 View Full Answer
