Question 1135177
.
<pre>
If  {{{alpha}}} is the elevation angle (in degrees), then


    {{{tan(alpha)}}} = {{{H/L}}},


where  H  is the flagpole height  and  L  is the cast length.


In your case  H= 74 ft,  L = 59 ft,  so


    {{{tan(alpha)}}} = {{{74/59}}} = 1.254.


It implies  {{{alpha}}} = arctan(1.254).


Use your computer or calculator to find  {{{alpha}}}.
