Components of Vectors

An airplane flies at 65 meters per second in a direction 149 degrees counterclockwise from east. What are the east and north components of the plane's velocity? The book's answer is: -200 m/s for its east velocity and 120 m/s for its north velocity. Can you confirm whether this is correct and show its solution? The book does not show the solution.
