What is the value of x, the side length of the smallest square (please show work) Thanks!
Ratling [72]

Answer:

8 cm

Step-by-step explanation:

Ok lets on the biggest square we have 17 cm

17cm is the hypotenuse for the right triangle

The second largest's area is 225 cm^2

Sq root of 225 cm^2, is 15

To find x, lets plug the info we have to the pythagorean theorom

a^2 + b^2 = c^2\\a^2 + 15^2 = 17^2\\a^2 + 225 = 289\\\\289 - 225 = a^2\\64=a^2\\a = 8 cm

The side length of the smallest Square is 8 cm

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

A = {1, 3, 5, 7, 9}
kondor19780726 [428]
The \cap symbol means intersection, so everything that is in both sets, and the \cup symbol means union, so the two sets combined.

B \cup C = \{1, 2, 4, 5, 6, 7, 8, 9, 10\} = S
A \cap S= \{1, 5, 7, 9\}

So the answer is A.
