Question

Solve for x. (Round to the nearest tenth)

Answer 1

13.7

Explanation:

fill the numbers in using pythagorean theory

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

(the hypotenuse has to be
`c^(2)`)

`9.2^(2) + b^(2) = 16.5^(2)`

`84.64 + b^(2) = 272.25`

`b^(2) = 187.61`

(to get
`b` alone you have to find the square root of both sides)

`b = 13.69707`

round that and you get

`b = 13.7`!
