do we use the Pythagorean theorem or the tan law?

We need the tangent here

 

The shadow length is the adjacent side  to the angle and we are  trying to  find the opposite side....so...

 

tan (43)  = Tree  Height

                 ___________             multiply bothsides by 9.3

                        9.3

 

9.3 * tan (43)  = Tree Height  ≈   8.67 m

 

 

cool cool cool
