The total electric field consists of the vector sum of two parts. One part has a magnitude of E1 = 1300 N/C and points at an angle %u03B81 = 35o above the +x axis. The other part has a magnitude of E2 = 1800 N/C and points at an angle %u03B82 = 55o above the +x axis. Find the magnitude and direction of the total field. Specify the directional angle relative to the x axis.
