Answer:
Step-by-step explanation:
Let x represent the sun's angle of elevation.
We have been given that a 6-foot tall man casts a shadow that is 12 feet long.
Upon looking at our attachment we can see that man and his shadow forma a right triangle with respect to ground, where height of man is opposite side and his shadow is adjacent side.
Since tangent relates opposite side of a right triangle with adjacent, so we can set an equation as:
Using arctan we will get,
Therefore, the measure of the sun's angle of elevation is 27 degrees.
B.f(x)=-1/3x^4+7x^2+15
Step-by-step explanation:
You can use a graph tool to graph the function a visualize the behavior.
Using a graph tool, the function,.f(x)=-1/3x^4+7x^2+15 could possibly have created the graph. See attached graph for the function.

Answer:
Hello! answer: x = 40
Step-by-step explanation:
These are vertical angles meaning they will have the same measure.
40 × 3 = 120 120 - 16 = 104 therefore x = 40 hope that helps!
