Linear pairs add up to 180 degrees.

7w - 20 + w + 100 = 180

8w + 80 = 180

8w = 100

w = 12.5

BNR = 7w - 20 = 87.5 - 20 = 67.5

RNA = w + 100 = 112.5

RNA is bigger by 112.5 - 67.5 = 45.

w = 12.5, BNR = 67.5, RNA = 112.5,

RNA is bigger by 45 degrees.

Which elements in the set below are integers? –3, 3.7, √ 81 , –7.34, √ 8 , 5, 56⁄7, –1 A. –3, √ 81 , 5, 56⁄7, –1 B. 3.7,√ 81 , √
Doss [256]

The answer is:  A. –3, \sqrt{81}, 5, \frac{56}{7}.

The explanation is shown below:

1) By definition, the integers include whole numbers, negative numbers and zero.

2) Therefore, keeping this information on mind, you have that:

-3 is a negative number without decimal part, therefore, it is an integer.

3.7 is decimal number, so it is not an integer.

\sqrt{81}=9 (It is a whole number, therefore, it is an integer).

-7.34 is a decimal number, so it is not an integer.

\sqrt{8}=2.828 is an irrational number. It is not an integer.

5 is a whole number, therefore, it is a integer.

\frac{56}{7}=8 (It is a whole number, then, it is an integer).
