it is neither arithmetic nor geometric.
But common difference is arithmetic.
They are supplementary angles.
<span>Distance formula is used to prove that line segments are congruent and the lengths are equal.
Here is the distance formula :
</span><span>sqrt [(x2-x1)^2 + (y2-y1)^2]
</span>Hence the right answer is :

Answer:
22
Step-by-step explanation:
You do maths
27x - 144 + 15 = 6x - 24
27x - 129 = 6x - 24
+129 +129
--------- --------
0 105
27x = 6x + 105
-6x -6x
----- ------
21x 0
21x = 105
21x/21 = 105/21
x = 5
