Answer:
2,880
Step-by-step explanation:
To calculate the sum of the interior angles of any polygon, we can use the following formula:
(n - 2) x 180
Where n = number of sides
Here, we want to find the sum of the interior angles of an 18-sided polygon.
This means that the number of sides is 18 so n = 18
We can now use this information to plug it in to the formula and simplify
(n - 2) x 180
==> plug in n = 18
(18 - 2) x 180
==> subtract 2 from 18
16 x 180
==> simplify multiplication
=2,880
Answer:
B. 2,880°
Step-by-step explanation:
The interior angle formula is (n - 2) × 180.
Here, "n" represents the number of sides.
Thus, we would first solve 18 - 2, which equals 16.
Then, we solve 16 × 180, which equals 2880.
Hence, the answer is B. 2,880°.
