Question 1013047
"...from a certain point on the ground that the angle of elevation of the top of the pole is 35 degree."


What certain point on the ground?  Where the cadet is standing?  Make this clear.  If this is the 130 meter from the base of the pole, then {{{y/130=tan(35)}}}.


Also, how tall is the cadet?  Angle from his feet or from his head?
