1/2x-1/4y=10, 1/8x-1/8y=19 which ordered pair satisfies the system of equations?

Please add an explanation.

false

step-by-step explanation:

the reason i say this is because for a certain length of sides you can pick any two and the length is wither equal or greater than the third side and in this case it's not.

3 + 5 = 8

8 is smaller than 9 which is the third side.

hope this : )

11) obtuse

13)right

15) acute
