Question

From the top of the building the angle of elevation of the top of the cell tower is 45 and the angle of depression to its foot is 60 . If the height of the cell tower is 46m then find the distance between building and tower and height the building

Answer 1

dear guy!
the answer is similar but not same:
Since angle of dipression is 45deg
height of the building would be 7m
now angle of elevation is 60deg
tan 60=x/7
√3=x/7
x=7√3m
height of the tower is 7+7√3
                                 7(1+√3)
                                 7(1+1.73)
                                7*2.73
                                19.11m
