A rotation about 270 degrees CW about the origin and 90 CCW about the orgin.

Step-by-step explanation:  Using the rules of 90 degrees Counterclockwise

(x,y)⇒( -y,x)

D is 3,2 then it  goes to  -2,3 which were A is

E is 3,7 then it goes to -7,3 which C is at

F is 10,5 then it goes to -5,10 where B at.

Also it 270 CW because 270 CW is the same as 90 CCW.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
