Answer: Angle of elevation of sun at that time is 24.51° .

Step-by-step explanation:

Since we have given that

Height of a large totem pole near Kalama, Washington = 100 feet

Length of a shadow at noon = 219 foot

We need to find the angle of elevation of sun at that time .

As we know the formula for "Tangent ":

$\tan\theta=\frac{AB}{BC}\\\\\tan\theta=\frac{100}{219}\\\\\tan\theta=0.456\\\\\theta=\tan^{-1}(0.456)\\\\\theta=24.51\textdegree$

Hence, Angle of elevation of sun at that time is 24.51° .
