Add three vectors A, B, and C, where R=A+B+C. Calculate the X-component of the resulant. A=12.6 m/s at 100.6 degrees from the positive X-axis B=7.6 m/s at 285.6 degrees from the positive X-axis C=38.4 m/s at 41.0 degrees from the positive X-axis The X-component of the resultant R in m/s, round to one place past the decimal
