The e vertex of the decagon will be in the top position after rotating it counterclockwise by 3 times the smallest angle of rotation.
Which vertex will be in the top position of the regular decagon?
A regular decagon has 10 sides of equal lengths with points labeled 'a' through 'j' clockwise. It is given that the point a is the top-left point. Hence, the the vertex which is in the the top position currently is 'b'.
Now, the smallest angle of rotation will be the angle between the two sides of the decagon.
In the first rotation by the smallest angle in counterclockwise direction, point 'c' will come to the top position. In the second rotation by the smallest angle in counterclockwise direction, point 'd' point will become the top most vertex. Finally, after the third similar rotation, 'e' vertex will be in the top position of the decagon. (Refer the attached diagram)

ANSWER: Multiply and Divide from left to right
To do this question we must follow the rules of PEMDAS. The first step would be to evaluate the equation given to us in the parentheses. To solve that we would have to use PEMDAS once again which tells us to multiply 2 x 2 before we add 3, so we get 7. Now that there is no more Parentheses, our second step is to evaluate each Multiplication and Division expression from left to right. This would start by dividing 63 by 7 to get 9.
Answer:
9b≥ -18
Step-by-step explanation:
B is considered as a variable as in like a+b= c
The number is 0.

The steps to be followed for synthetic-divisions are:
Step 1:
The 1st row is filled with numbers taken from a polynomial equation.
Step 2:
The 2nd row is to be filled with required numbers to solve the answer row.
Step 3:
Now to fill the second row, just write down the 1st number in the 1st row in the answer row as it is.
Step 4:
Then the constant (in this problem, it is -2 ) is multiplied with the 1st number in answer row = (1*-2 =-2)
Step 5:
The obtained number is entered in the 2nd row.
Step 6:
Next, do addition of 1st and 2nd row = (-2) + (-2)= -4
Step 7:
Repeat the steps until the end of answer row. (-4*-2= 8) , (-8)+(8)=0 , (0*-2=0) , (5+0= 5)
Solution:
-2| 1 -2 -8 5
-2 8 0
__________
1 -4 0 5
