Answer:
20 feet
Step-by-step explanation:
In this case, you'd use pythagoras's theorem (a^2 + b^2 = c^2)
The hypotenuse is always = c, so you'd set up the equation like this:
16^2 + 12^2 = c^2, where you're solving for c (to find out the length of the kite string)
This equation simplifies to 256 + 144 = c^2
which further simplifies to 400 = c^2
to solve for c, we square root both sides so the c is isolated:
20 = c
so the length of the kite string is 20 feet
