Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
<h3>

</h3>
<u>Expand the terms in the bracket</u>
That's
<h3>

</h3>
Move - 2x to the left side of the inequality to make it positive
<h3>

</h3>
<u>Add 4 to both sides</u>
That's
<h3>

</h3>
<u>Divide both sides by 8</u>
<h3>

</h3>
We have the final answer as
<h3>

</h3>
Hope this helps you
6 x 9 x i = 54i
4(i) x 2(i) = 8i^2
54i +8i^2= 8i^2 +54i
Here, sum of all the angles would be equal to 360.
We can see there are two right angles (=90)
So, 90 + 90 + x + 60 = 360
240 + x = 360
x = 360 - 240
x = 120
In short, Your Answer would be 120
Hope this helps!
