height = 6 m
base = 2root3 m
then ,
p/b = 6/2root3 = 6 x 2root3 / 2root3 x 2root3 = 6 x 2root3 / 12 = root3
tan 60 = root3
therefore, the sun's elevation is 60 degree.
base = 2root3 m
then ,
p/b = 6/2root3 = 6 x 2root3 / 2root3 x 2root3 = 6 x 2root3 / 12 = root3
tan 60 = root3
therefore, the sun's elevation is 60 degree.

angle of elevation of sun = @
then ,
tan@ = height of pole /length of shadow
tan@ = 6/2root3
=root3 =tan60
@ = 60 degree
then ,
tan@ = height of pole /length of shadow
tan@ = 6/2root3
=root3 =tan60
@ = 60 degree
