We have the supplementary angles.

The sum of the measures of the two Supplementary Angles is 180°.

Therefore we have the equation:

13x - 2 + 39 = 180

13x + 37 = 180 <em>subtract 37 from both sides</em>

13x = 143 <em>divide both sides by 13</em>

<em>x = 11</em>

<h3>Answer: 11</h3>

Write an equation for the nth term of the arithmetic sequence. Then find a 30

AnnZ [28]

Answer:

The nth term is given by: $a_n = -9 + 3(n-1)$

The 30th term is 78.

Step-by-step explanation:

Arithmetic sequence:

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n-1)d$

In which $a_1$ is the first term and d is the common difference between terms.

-9, -6, - 3,0

This means that $a_1 = -9, r = -6 - (-9) = -6 + 9 = 3$ . So

$a_n = -9 + 3(n-1)$

30th term:

$a_30 = -9 + 3(30-1) = -9 + 87 = 78$

The 30th term is 78.
