  Height of the Pole = x
  Length of the shadow = x√3
  
  Imaginary side connecting the tip of the pole and the end of the shadow = 2x
  Because it is a 30,60,90 special right triangle
  
  Therefore the angle elevation of the sun = 30

  The angle of elev. is 30 because the triangle is 30 60 90 triangle, the pole is the shot leg which is x
