When you subtract 4 from 8 you get 4 and this when you add 9 your final answer is 13.
Answer: A. 90° clockwise, E. 270° counterclockwise
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the Double Angle Identity: cos 2A = 2cos²A - 1
Use the Difference Identity: cos (A - B) = cosA · cosB + sinA · sinB
Use the Unit Circle to evaluate: cos (π/2) = 0 & sin (π/2) = 1
<u>Proof LHS → RHS</u>

LHS = RHS: sin A = sin A 
4.572 kilometers is the answer.
