9.9

Explanation:

Answer 2

Hi there!


`{s}^(2) + {s}^(2) = {d}^(2)`
According to the Pythagorean Theorem,

`{a}^(2) + {b}^(2) = {c}^(2)`
so this statement is true.


Since

`{s}^(2) + {s}^(2) = {d}^(2)`
and s = 7, then

`{7}^(2) + {7}^(2) = {c}^(2)`
simply:

49 + 49 = c^2
98 = c^2
c = sqrt (98)

Hope this helps!
