An observer (O) is located 400 feet from a building (B). The observer notices a kite (K) flying at a 29° angle of elevation from his line of sight. How high is the kite flying over the building? You must show all work and calculations to receive full credit

Answer :

Check the picture below.

[tex]\tan(29^o )=\cfrac{\stackrel{opposite}{h}}{\underset{adjacent}{400}}\implies 400\tan(29^o )=h\implies {\LARGE \begin{array}{llll} \stackrel{ft}{221.72}\approx h \end{array}}[/tex]

Make sure your calculator is in Degree mode.
