Answer:
14.14
Step-by-step explanation:
The diagonal of a square is √2 times the side length.
AC = AB×√2
AC = 10√2 ≈ 14.14
_____
The diagonal of a square is the hypotenuse of an isosceles right triangle. If the sides of that are s and the diagonal is d, the Pythagorean theorem tells us ...
d² = s² + s²
d² = 2s²
d = (√2)(√s²) = s√2
This relation holds for <em>any isosceles right triangle</em>, not just for the diagonal of this square. It is useful to remember.
Guessing this is a combined work problem??? You forgot to post the question. I can solve for the time it takes them to complete the house together..
1/3 + 1/5 = 1/t
5/15 + 3/15 = 1/t
8/15 = 1/t
15/8 = t
