Answer: x = (-3,3), y = (-5,5)
Step-by-step explanation:
Add both of the equations together, for
. Now we can divide both sides by 3, getting
. we subtract the first equation from our equation we just got, getting
y= (5,-5). once we plug that in, we get
,
x = (-3,3)
The correct answer would be 3, if im not mistaken
Side 1+ side 2 + side 3=180 on a triangle. 180-56=124 124-66 because 124-56 =66 but X is the smaller side so 56 X=56 (i believe but could be wrong unsure I have a tendency to mess up a few calculations.)
