Answer:
angle A + angle B = 180 degrees is correct
Step-by-step explanation:
Answer:
1/2 (-sin2x - cos 2x)
Step-by-step explanation:
Distribute 1/2 to every term in the parentheses
The another way to state the transformation would be 
<u>Solution:</u>
Rotation about the origin at
: 
The term R0 means that the rotation is about the origin point. Therefore, (R0,180) means that we are rotating the figure to
about the origin.
So, the transformation of the general point (x,y) would be (-x,-y) when it is rotated about the origin by an angle of
.
Hence according to the representation, the expression would be
.
