By creating two right triangles (one for depression and one for elevation) and by using 700 as the adjacent side, you can use tangents to find the opposite sides and add them together.
Tan(45) = opposite side/700 or 700tan(45) = opposite side (elevation).
This of course equals 700.
Then do the same for the depression.
Tan(32) = opposite side/700 or 700tan(32) = opposite side (elevation).
Which equals 437.4.
Adding the two together and you get the height of the cell tower at 1137.4ft

Step-by-step explanation:
Sin 30 = k/16
k = 16 x sin 30
k = 16 x (0.5) = 8
