Acell phone tower that is 150 ft tall sits on a mountain that
is 1200 ft above sea level. what is the angle of depression from
the top of the tower to a cell user 5 miles away and 400 ft above
sea level?

angle of elevation will be

Step-by-step explanation:

Given,

height of tower = 150 ft

height of tower = 1200 ft

So, total height of peak of tower = 1200 + 150

                                                       = 1350 ft

distance of user from cell tower = 5 miles

                                                     = 5 x 5280 feet

                                                     = 26,400 feet

Since the height of user from sea level = 400 ft

so, height of peak of tower with respect to user = 1350 - 400 ft

                                                                                = 950 ft

If the angle of depression is assumed as , then we can write

So, the angle of elevation will be

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted
