Sum Of The Altitudes Of Triangle Is Less Than He The Sum Of The Sides Of The Triangle.
(ae+cf+bd < Ab+bc+cd)
I Have Tried With
Sum Of The Two Sides Is Greater Than The Third Side
Abc As Sides Of The Triangle And Ae. Bd And Cf As The Altitude.
Ae+ec>ac Bd+dc>bc Cf+af>ac
Ae+be>ab Bd+ad>ab Cf+fb>bc
Adding All I Got 2ae+2bd+2cf>ab+bc+ca
First Of All Sorry For The Late Reply. It Was From "cbse All In One Exam Practice Sums". Many Teachers From The School Also Tried The Sum But Could Not Reach The Answer. So Whenever I Stuck With Any Sum I Post It In This Site . And Definetly I Got The Solution. May Be The Sum Is Wrong.

1) The angle of elevation of a cloud from a point h metres above the surface of a lake is x and the angle of depression of its reflection in the lake is y. Prove that the height of the cloud above the lake is h(tany+tanx)/(tany-tanx)
2) A ladder rests against a vertical wall at an inclination x to the horizontal . Its foot is pulled away from the wall through a distance p so that its upper end slides a distance q down the wall and then the ladder makes y to the horizontal.
show that p/q=cosy-cosx/sinx-siny
