Final answer:
To find the angle of elevation theta of the sun at a specific time of day, we can use the concept of similar triangles.
Step-by-step explanation:
To find the angle of elevation theta of the sun at a specific time of day, we can use the concept of similar triangles. Let the height of the flagpole be h and the length of its shadow be s. We can set up the proportion:
h/s = tan(theta)
Substituting the given values, we get:
23/16 = tan(theta)
To find theta, we can take the inverse tangent of both sides of the equation:
theta = atan(23/16)
Using a calculator, we find that theta is approximately 57.75 degrees.
