Expert Answer:

dear student,
can't figure out your question.
perhaps you want to know what is the angle of elevation if the height of a tower is equal to its shadow.
consider a tower AB.(A the top of the tower, B is the point on the base)
and its shadow BC on the ground.
then angle ACB becomes the angle of elevation  of the top ,right?
so then ,
tan (ACB)=AB/BC=1....from given info.
so angle ACB=45 degrees.as tan 45=1.
 hope this is what you wanted to know.
all the best...
