We know the adjacent side to the angle  = 40

And we are looking for the opposite side to the angle = tree height

The trig function that relates the opposite / adjacent  =  tangent

 

So

 

tan ( 50°)  =  opp / 40        multiply both by 40

 

40 tan (50°)  =  opp   = tree height  ≈  47.7 ft

 

 

cool cool cool
