Question 1203029
.
Leilah, who is 1.7 m tall, is standing 8 m from a 5 m tall tree. 
She looks up to the top of the tree and measures the angle of elevation. 
What measure did she find?
~~~~~~~~~~~~~~~~



        The solution by josgarithmetic is wrong.

        I came to bring a correct solution.



<pre>
The illustration is a right angled triangle with vertical leg of  5-1.7=3.3 meters 
and horizontal leg of  8 meters.


Therefore, for the angle of elevation x we have this equation

    tan(x) = {{{vertical_leg/horizontal_leg}}} = {{{3.3/8}}} = 0.4125.


It gives for the angle of elevation x

    x = arctan(0.4125) = 22.42°  (rounded).    <U>ANSWER</U>

Solved.

Ignore the solution by @josgarithmetic, for the safety of your mind.
