A particle undergoes three displacements. The first has a magnitude of 15m and makes and angle of 35 degrees with the positive x axis. The second has a magnitude of 7m and makes an angle of 163 degrees with the positive x-axis. After the third displacement the particle returns to its initial position.(adsbygoogle = window.adsbygoogle || []).push({});

Find the magnitude of the third displacment. Answer in units of m.
