Question

"Give your answers to 1 decimal place" help :(​

Answer 1

Explanation:

`12^(2) + b^(2) = 17^(2) \\144 + b^(2) = 289\\b^(2) =289-144\\b^(2) =145\\b=√(145) \\b = 12.04\\b = 12`

Hope it helps tell me if its right

Answer 2

`b` ≈
`12.0`

Explanation:

Using the Pythagorean theorem:
`a^2+b^2=c^2` where a and b are the legs and c is the hypotenuse.

`12^2+b^2=17^2\\144+b^2=289\\`

Subtract 144 from both sides

`b^2=145\\`

Square root both sides

`b=√(145)`

`b` ≈
`12.0`
