Answer: <u>A. 12/35....................</u>
Assuming rotation is about origin, then
R180: (x,y)->(-x,-y)
So
A(6,8)->A'(-6,-8)
B(6,12)->B'(-6,-12)
C(10,12)->C'(-10,-12)
you have to add 90 +90 3 times then theres your answer :)
I believe the first one is h becuase there is a y on the left side.
for the second one just find the slope for the points and see which one doesn't fit in the groups (I would use tables)
and for the last one try writing equations for them.
but idk tho that's just what I would do.
R(B+T)=E because you first have to add T to both sides then multiply R to cancel out the division sign
