Suppose z is a complex number (a point in the plane) with angle 30 degrees and radius 2. Suppose w is a complex number with angle 60 degrees and radius 5. If z and w are multiplied together the angle of their product is how many degrees? Answer value

Write each number in complex polar form:

When you multiply two exponential expression with the same base (here, that's e), you end up adding the exponents, so that

so the angle of the product zw is 90°.
