Measuring Sun Angle
How high in the sky is the Sun?
12:15 P.M. PDT, May 13, 2004, Lower Columbia College
The 12 inch ruler, held at a right angle by a block of wood,
casts a 6.7 inch shadow.
Trigonometry yields the answer.
Opposite side divided by adjacent side equals the tangent of the angle.
The opposite side is the ruler, 12.0 inches.
The adjacent side is the shadow of the ruler, 6.7 inches.
12.0/6.7 = 1.79045
This is the tangent of an angle of 60.8 degrees.
