<u><em>hope this helps>3</em></u>
Step-by-step explanation:
The correct answer is option D ,x = 12°
Given : Two straight lines intersecting at common point.
To find = x
Solution :
When two straight lines intersect each other at same point their vertically opposites angle are equal.
So, according to image figure given:
The value of x = 12°
Since the above sequence is a geometric sequence
For an nth term in a geometric sequence
That's
where
r is the common ratio
a is the first term
n is the number of terms
From the question
a = 4.05
r = 1.35 / 4.05 = 0.33
Substitute the values into the above formula
We have

-78
We subtract 1, then 3, then 5, then 7
Then subtract 9,11,13,15,17
-21 -11 = -33
-33 -13 = -46
-46 -15 = -61
-61 -17 = -78
3, 2, -1, -6, -13, -22, -33, -46, -61, -78
