Answer:
C.) 4 sqrt2
Step-by-step explanation:
ON=MN
therefore you can use pythagereum theorum here in a right triangle
as the hypotnuese is 8 you know that ON and MN is equal to the sqrt of 32 each. As A^2+ B^2=C^2
C=8 so C^2= 64 therefore,
A^2+ B^2=64 therefore,
A^2= 32 and B^2=32
you take the sqrt of 32 you get 4sqrt2
The answer would be 2.
The difference means you subtract the two numbers.
Absolute value makes the numbers within into a positive number.
The equation would be 8-6=2
