Hi, I've figured out An equation that is 84 is 99 fewer than a number c which is 84+c-99. What I need help on is to figure out what C=, if you can help me please do!

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

i dont know if you cant find a way its best to actually add all of them start from 105 tho
