Answer:
I really hope this help! Some may call it front end rounding while others call is front end estimating, even though they mean the same thing. When rounding a place value, you need to look to the number to the right of it. Example: Most often a teacher may as you round the number 452 to the nearest ten’s. That number will than be 450. But why? Well as we look at the number, we know we need to round to the nearest ten. So in our case it would be 52. Our rule to remember when rounding is 5 and higher we round-up. Since we are looking at the portion of the number 52, we go right of the tens place to find the number 2. Since the number 2 is not 5 or higher, we round down making it 50. Don’t forget to finish the problem by adding the hundreds back to the original number. Your answer for this problem is 450.

Answer:
5091.4 if rounding, then idk
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
