Can someone help me please?

B) x = 2√2, y = 2

Step-by-step explanation:

The easiest way to solve this is to see that because one corner is 90 degrees, and the other 45, then the third one must also be 45.  This means that the two sides on the right angle are the same length, so y = 2.

With that then, you can use the Pythagorean theorem to solve for x:

So the correct answer is b.  x is equal to two root two, and y is equal to two.

81.2222 or 81 with 2 left over

Step-by-step explanation:

231/9 = 81.2222

81.2222 rounded down = 81

81*9 = 729

731-729 = 2 left over
