Blababa [14]4 years ago
5 0

Answer:

<u>a = 13</u>

Step-by-step explanation:

We should know that: The sum of the interior angles of the triangle = 180°

Given the measure of the angles: (6a - 2) , (5a - 13) and (5a - 13)

So,

(6a - 2) + (5a - 13) + (5a - 13) = 180°

16 a - 28= 180               ⇒ Add 28 to both sides

16 a = 180 + 28 = 208  ⇒ Divide both sides by 16

a = 208/16 = 13

Add all the numbers together:
5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10= 136

divide the total with the total amount of numbers

136/17 = 8

Now add all the numbers again WITH the one

5 + 5 + 6 + 7 + 7 + 7 + 7 + 8 + 8 + 8 + 9 + 9 + 10 + 10 + 10 + 10 + 10 + 1= 137

Divide the total amount with the amount of numbers there are

137/18 = 7.61

7.61 < 8

The mean book rating will decrease by 0.39

PolarNik [594]

Answer:

In this passage, Alliteration is present in the words "nodded, nearly napping".

Step-by-step explanation:

Alliteration is defined as the repeated sound of the first consonant in a series of multiple words, like here in - "nodded, nearly napping" -(all starting with 'n')

Or we can also say that it is the repetition of the same kind of sound at the beginning of words or in stressed syllables.

So, the correct option is C. the words nodded, nearly napping are right next to each other and are stressed.
