Question 1203327
.
The angle of elevation to the top of a building in New York is found to be 13 degrees 
from the ground at a distance of 1 mile from the base of the building. 
Using this information, find the height of the building. (Round your answer to four decimal places.)
~~~~~~~~~~~~~~~~~~~~~


<pre>
1 mile = 5280 feet.


tan(13°) = {{{H/D}}} = {{{H/5280}}}.


H = 5280*tan(13°) = 5280*0.23086819112 = 1218.984 feet = 1219 feet (rounded).    <U>ANSWER</U>

Solved, by applying simplest trigonometry.



&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;It is a kind of madness to request four decimal places in such problem.
