Answer:
See below
Step-by-step explanation:
It could be a positive square root l like √10 ( the number not being a perfect square).
He would have obtained this value from the application of the Pythagoras theorem. For example the length and width of the rectangle might have been 3 and 1 foot respectively, so the diagonal would have length √(3^2 + 1^2) = √10.
He could give an estimate of the length to nearest hundredth using his calculator. This would be 3.16 feet.
The answer is 125/18. decimal form would be 6.94 (repeating) lol
the 3th choice because it does not add up to 180, it actually adds up to something greater
The answer would be 105, it's square root is approximately 10.2469 <span />
