Final answer:
To calculate the angle of elevation, use the tangent function with the height of the fence and the height of the tree.
Step-by-step explanation:
To calculate the angle of elevation of the top of the tree from the top of the fence, we can use trigonometry. Let's label the height of the fence as 'a' and the height of the tree as 'b'.
We can use the tangent function to find the angle. Tan(angle) = b/a. In this case, a = 2.4m and b = 16m. Plugging in the values, we get: Tan(angle) = 16/2.4. Solving for angle, we find that the angle of elevation is approximately 75.96 degrees.
