Find the argument of the complex number -3–9 in the interval 0°< ϴ < 360°, rounding to the nearest tenth of a degree if necessary.

Step-by-step explanation:

Complex Numbers

They are expressed as the sum of a real part and an imaginary part:

Complex numbers can also be expressed in polar form:

Where r is the modulus of the complex number and θ is the argument.

The argument can be calculated by:

The angle θ must be calculated in the appropriate quadrant depending on the signs of the real and imaginary parts.

The complex number is given as:

Here: a=-3, b=-9

Since both components are negative, the argument lies in the third quadrant (180° < θ < 270°).

The calculator gives the answer 71.6°, we need to adjust the angle to the third quadrant by adding 180°, thus
