Final answer:
The length of Kyle's shadow is 1.5 feet.
Step-by-step explanation:
To find the length of Kyle's shadow, we can set up a proportion using the given information from the monument's shadow.
If the monument's height is 64 feet and its shadow is 16 feet long, we can set up the proportion as follows:
(Kyle's height) / (Kyle's shadow length) = (Monument's height) / (Monument's shadow length)
Plugging in the values, we get:
(6.25 feet) / (x) = (64 feet) / (16 feet)
Cross-multiplying and solving for x, the length of Kyle's shadow, we get:
x = 1.5 feet
