Answer:
13-gon
Step-by-step explanation:
The sum of the interior angles of a polygon with n sides is:
S = 180° (n − 2)
If S = 1980°, then:
1980° = 180° (n − 2)
11 = n − 2
n = 13
Answer:13

Answer:
im pretty sure its C. X=4 but im not positive.
The value of 3 in 6300 is ten times the value of 3 in 530
Place value and total value
For example;
In the number; 13,548, the place value of the digits in the number are;
Ones -8
Tens - 4
Hundreds - 5
Thousands - 3
Ten Thousands – 1
1 x 10,000 = 10,000
3 x 1000 = 3,000
5 x 100 = 500
4 x 10 = 40
8 x 1 = 8
The sum of the total values of digits in a number will be equivalent to the value of that number.
In the question.
Comparing the value of 3 in 6,300 and 530
The value of 3 in 6,300 is 300 and
The value of 3 in 530 is 30
Therefore; the value of 3 in 6300 is ten times the value of 3 in 530

Topic: Place value and total value
Comparing the values of 3 in each of 6,300 and 530, we will have:
3 in 6300 is 3 hundreds while 3 in 530 is 3 tens
Place value is defined as the value of each digit in a number. For example, the 5 in 853 represents 5 tens, or 50; however, the 5 in 5,003 represents 5 thousands, or 5,000.
We want to compare the values of 3 in each of the numbers 6,300 and 530.
Thus, we can say that:
3 in 6300 is called 3 hundreds while 3 in 30 is called 3 tens or 30
