Spreadsheet with other people’s measurements as well as mine:

Length of shadow:
120 7/8 inches = 3.070225 meters

Height of pole:
50 1/8 inches = 1.274445 meters

angle = arctangent ( p / s )

Where:
p is the length of the pole
s is the length of the shadow

angle = arctan ( 1.274445 / 3.070225) = 22.54325°
