What is the relationship between vectors, complex numbers and polar coordinates? (100 points)

here is a answer

Step-by-step explanation:

There is also a connection betweenmultiplication of complex numbers and polar coordinates. As usual, polar coordinates of a point ( x , y ) in the plane are defined as ( r , θ ) where r is the length of the vector ( x , y ) and θ is the angle this vector makes with thepositive x axis.

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
