Can someone me find the value of x?
!

x = 7

Step-by-step explanation:

The segment joining the midpoints of the 2 sides of the triangle is one half the length of the third side, that is

2x - 6 = 8 ( add 6 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
