Answer:

The correct answer is B. 30.

Step-by-step explanation:

538 - 509 = 29

Since we need to round this to the nearest tens place, that means we need to round it to 10, 20, 30, etc.

When rounding a number, you look at the last number in it. If it is a <em>5 or higher</em>, you <em>round up</em> the number before it by 1. If it is a <em>4 or lower</em>, the number before it<em> stays the same</em> and the <em>lowest number</em> turns into a 0.

Since 9 is <u><em>higher</em></u> than 5, the 2 in 29 will turn to a 3, and the 9 will turn into a 0.

Therefore, the correct answer is B. 30.

Hope this helps! :D

Answer:

n = 18

Step-by-step explanation:

The formula for angle sum of a polygon is S = 180 (n - 2), where S is the sum and n is the sides.

We are given that the sum is 2880, and are trying to find n.

Simply sub in S = 2880,

2880 = 180 (n - 2)

Divide by 180 to get (n - 2) by themselves on the right side,

16 = n - 2

Now add 2 to the other side to get n by itself

18 = n

n = 18

Hope this helped!! Please feel free to ask me if there's anything you don't understand from this working
