Answer 1

Answer: 14.9

Explanation:

The Pythagorean Theorem formula is
`a^2+b^2=c^2`. a and b are the legs, and c Is the hypotenuse. Looking at the figure, we are only given the legs, and asked to find the hypotenuse. All we have to do is to substitute and solve.

`10^2+11^2=c^2` [exponent]

`100+121=c^2` [add]

`221=c^2` [square root both sides]

After plugging this into the calculator, we get 14.9, rounded.
