Selena is flying a kite as shown below. Use the measurements to find how long the kite string is. 16 feet
12 feet
feet

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

answer: 1inch=7days
