A teenage boy is 6 ft tall and casts a shadow of 8ft. What is the distance from the top of his head to the end of his shadow?

10 feet

Step-by-step explanation:

This image forms a special right triangle: 3-4-5. This represents the ratios of the sides.

Multiplying 3-4-5 by 2, you get 6-8-10. 10 is the hypotenuse (the answer you want) and the only number not listed in the problem.

this doesn't make sense lol

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
