Question 979991


You know the horizontal distance &nbsp;<B>L</B> = 1800 meters. 
It is the leg of a right-angled triangle.


And you also know the angle &nbsp;{{{alpha}}} = 10°40'.
It is the angle of the right-angled triangle.


You need to find the other leg of the right-angled triangle &nbsp;<B>h</B>, &nbsp;which is the height &nbsp;(the altitude).


Use the Trigonometry function &nbsp;<B>tangent</B>: &nbsp;&nbsp;{{{h}}} = {{{L}}}.{{{tan(alpha)}}} = 1800*tan(10°40') . . . 


Please complete yourself these calculations.


Good luck!
