Question 1106765
You are standing 49 meters from the base of a building. You estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82°. If the total height of the building is another 121 meters above the 86th floor, what is the approximate height of the building? (Round your answers to one decimal place.)
---------------
Sketch the picture.
You have a right triangle with base angle = 82 deg, base = 49 meters.
Find the height::
height = base*tan(82)
h = 49*7.115 = 348.65 meters (height to top of the 86th floor)
-----
Total height = 348.65 + 121 = 469.65 meters = 469.7 meters when rounded
