What rotation maps quadrilateral ABC to A'B'C'? (Check all that apply.)

A) Rotation of 270 degrees counterclockwise

B) Rotation of 270 degrees clockwise

C) Rotation of 90 degrees counterclockwise

D) Rotation of 90 degrees clockwise

E) Rotation of 180 degrees

Answer (B) and answer (D) apply

Step-By-Step explanation:

You can take the x and y values of the points and use them on the opposite axis, depending on how many times you would have to use them on the opposite axis you can determine how much rotation is needed (Every time you use the points on the opposite axis it is equivalent to 90 degrees).

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse

ratio is 2 : 9

the answer is three

13.5 : 3
