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 ":

Hence, Angle of elevation of sun at that time is 24.51° .
12x8=96 then 96 divided by 20=4.8, so the answer is 4.8, your welcome! Hopefully you get it right!!☺️
Obtuse angles measure more than 90 degrees, scalene angles have three different side lengths. Would you like for me to include angle measure in the sketch?
