Answer:
Step-by-step explanation:
(6-2i)(2-3i)=
we will use foil to multiply
-12-18i-4i+6(i^2)=
now remeber that (i^2)=-1
=12-22i-6=<u>6-22i</u>
<h3>Add Two-thirds to both sides</h3>
<em><u>Solution:</u></em>
<em><u>Given is:</u></em>

We have to find how this can be solved for "x" in one step
Remember that,
We we add or subtract same number from both sides of a equation, the equation still remains true
Therefore, from given,

Add Two-thirds to both sides
Thus,

Thus, Add Two-thirds to both sides to solve the sum
Answer: 90 degrees
============================
Explanation:
Let x and y be the two angles. Because they are supplementary angles, this means x+y = 180. Also since we're told that the angle is its own supplement, we can say that y = x.
Consequently, we can replace y with x and solve for x like so:
x+y = 180
x+x = 180 .... y is replaced with x since y = x
2x = 180
2x/2 = 180/2
x = 90
This means y = 90 as well. As a check, note how
x+y = 90+90 = 180
which verifies our answer.
