Answer 1

Hello!

You can solve this using the Pythagorean Theorem.

The Pythagorean Theorem is
`a^(2) + b^(2) = c^(2)`

c is the hypotenuse
a and b are the other sides

Put in the values we know


`a^(2) + 6^(2) = 11.7^(2)`

Square the numbers


`a^(2) +36 = 136.89`

Subtract 36 from both sides


`a^(2) =100.89`

Take the square root of both sides

a = 10.044

Round to the nearest thenth

a = 10

The answer is 10

Hope this helps!
