Answer:
(a) The graphic representation is in the attached figure.
(b) .
(c) .
Step-by-step explanation:
(a) Given a complex number we know, from Euler's formula that . So, it is not difficult to notice that
so it is on the unit circumference. Also, notice that the Cartesian representation of the complex number is .
Now,
.
Notice that has the same modulus that , so it is on the unit circumference. Beside, its Cartesian representation is .
So, the points and are symmetric with respect to the X-axis. All this can be checked in the attached figure.
(b) Notice that
Then,
.
(c) Notice that
Then,
.
I think that this is what you're asking-
To find the distributive property is quite easy, just as long as you get the concept of it.
Lets try this.
7x6(y-4)
You take 6xy=6y
Now you take 6x-4=-28
You have
7x6y-28 if you are just doing distributive.
Hope this helped!:)

Answer:
83°
Step-by-step explanation:
Since angle x and angle y are supplementary angles,
x + y = 180°.
Since y = 97°
x = 180° - y = 180° - 97° = 83°
