thats what i thought but that's not right actually the angle of depression is angle C
and thats why the answer is 234

No the Car is C    the angle of depression is from the top of the building to the Car ..... as I labelled the diagram

...... and then the horizontal distance to C   is    

              tan52 = 300/distance

              distance = 300 / tan52 = 234.4 m

 

 

or    tan 38   =   distance / 300

          distance = 234.4 m

....apparently YOU didn't read my original  answer :

"Note that the angle of dpression from the top = the angle of elevation from C"
