The quotient of the complex numbers is 3[cos(240)+ isin(240)] option (D) is correct.
<h3>What is a complex number?</h3>
It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
We have two complex number is given.
The quotient of the complex numbers:
= 3[cos(320-80)+ isin(320-80)]
= 3[cos(240)+ isin(240)]
Thus, the quotient of the complex numbers is 3[cos(240)+ isin(240)] option (D) is correct.

The answer to this is x=3/16
This is a bit of a tricky one since we are working with thousandths as the denominator. First, we want the common denominator, so we can multiply 8/10 by 100 to get 1000 as that denominator. This gives 800/1000. Next, let's solve the whole numbers. You must add a negative number to a negative number if you want a smaller answer, so we add -5, which means we now have -14 and 800/1000. Now, we subtract absolute value of the larger negative, or our goal, -15 and 465/1000, minus 14 and 800/1000. This yields 665/1000. Now we can add this value to our previous subtraction of 5.
So, the answer is 5 and 665/1000.
