Question

What's the value of x to the nearest tenth? Question 12 options: A) 7.9 B) 9.7 C) 5.9 D) 8.1

Answer 1

The value is 9.7

Explanation:

Use the Pythagorean theorem.
`a^(2) + b^(2)= c^(2)`

a=7 b=x c=12

`7^(2) + x^(2)= 12^(2)`

`49+x^(2) =144`

`144-49=95`

`x^(2) =95`

`\sqrt{ x^(2)} =√(95)`

x=9.74679434481

x=9.7
