Any complex number
can be written in trigonometric form as

where
is the modulus of
and
is its argument, i.e. the angle
makes with the positive real axis in the complex plane.
We have

and

Then

Answer:
x=8
Step-by-step explanation:
Answer:
5/36
Step-by-step explanation:
Probability is the outcome that a event will occur
Probability = Expected outcome/Total outcome
Since two sided dice are rolled, the total outcome will be expressed as;
Total outcome = 36
Since we are to find the probability that the sum is 8, the values that gives a sum of 8a re;
(2,6)(6,2), (5, 3), (3,5), (4, 4)
The expected outcome = 5
Probability = 5/36
Hence the probability that the sum is 8 is 5/36
