Question

What does d equal to?

Answer 1

Answer:
`11\sqrt 2`

Explanation:

Since it's a right triangle, we are using the Pythagorean Theorem.

`a^(2) + b^(2) = c^(2)`

The two legs (A and B) are equal to 11.

`11^(2)+11^(2) = c^(2)`

121 + 121 = 242

242 =
`c^2`

121 is a perfect square, and to get 242 we multiply 2.

The square root of 121 is 11.

c =
`11\sqrt 2`
