Final answer:
To find the length of the shadow cast by the building, we can use trigonometry. The length of the shadow can be found using the equation x = 98 * tan 57°. Therefore, the length of the shadow is approximately 84.7 ft.
Step-by-step explanation:
To find the length of the shadow cast by the building, we can use trigonometry.
Since the sun is 57° above the horizon, we can consider it as the angle of elevation.
Let x be the length of the shadow. We can set up the following equation:
tan 57° = x / 98
Now, we can solve for x:
x = 98 * tan 57°
Using a calculator, we find that x ≈ 84.7 ft.
Therefore, the length of the shadow cast by the building is approximately 84.7 ft.
