Question 1138039
.
<pre>
You have a right angled triangle.


Its vertical leg is  H = 100 feet long (given; the height).


Its hypotenuse  L  is under the question.


The elevation angle is  35°  (given).


sin(35°) = {{{H/L}}}.


Hence,  L = {{{H/sin(35^o)}}} = {{{100/sin(35^o)}}}.


Now use your calculator to determine  sin(35°)  and to get the numerical answer.
