A tree that is 50 feet tall casts a shadow that is 60 feet long.
Find the angle of elevation, to the nearest degree, of the
sun.
Let
x ------> the angle of elevation
we know that
tan(x)=50/60 ------> opposite side divided by adjacent side
using a calculator
x=tan^-1(50/60)=40 degrees
therefore
the answer is
40 degrees
