Answer:
The angle of elevation of the sun is
.
Step-by-step explanation:
Let
be the angle of elevation of the sun as shown in the diagram.
Then the side length which is
feet is opposite to
and the side length which is
feet is adjacent to
.
Therefore we use the trigonometric ratio that involves the opposite and adjacent sides, which is the tangent ratio.


We solve for
to get,


To the nearest degree, the angle of elevation is 
Answer:
27.5
Step-by-step explanation:
70(0.80)^10 + 20 = 27.51619276 which s about 27.5
The answer is C. 3.11 because if you divide 15.55 divided by 5 you will get 3.11
