229

Step-by-step explanation:

All the angles of a 4 sided shape add up to 360 degrees.

So if you add 99 and 32 together, then subtract the answer from 360, you get 229.

sorry, i don't know i just need points, i'm new here. chao

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
