We can drop the absolute value and the signs, and the integer part if they're all the same, and then make a common denominator and check for a decreasing sequence.
10/12, 7/12, 5/12 -- Check decreasing
3 1/3, 3 2/3, 2 2/3 -- nope, increases then decreases
6 5/7, 6 3/7, 5 2/7 - Check, decreasing
11 7/10, 11 6/10, 10 3/10 -- Check, decreasing
Answer: A,C,D
90 degrees exactly. It is four 90 degree angles
What bro. thats not even a question
A^2 + b^2 = c^2
(6√2)^2 + (6√2)^2 = c^2
(36)(2) + (36)(2) = c^2
72 + 72 = c^2
144 = c^2
√144=√(c^2)
c = 12
