Answer: {x,y} = {2,-4}
[1] x - y = 6
[2] 2x + y = 0
Step-by-step explanation:
Centriod!

We know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
<span>the height of a triangle is 2*(x-2)</span>
