Hi gbedenba! Welcome to PF!

The quantity called the electric field is a vector. The electric field inside a scientific instrument is = (215 - 380 ) V/m, where V/m stands for volts per meter. What are the magnitude and direction of the electric field?

Do you mean that the x and y coordinates are 215 and -380?

Use Pythagoras, and tangent.
