Answer:

No solution (read below)

Step-by-step explanation:

Formula:

a_n = a_1 + (n-1)d

N is the term #

D is the common difference

First, let's find the common difference.

13 - (-15) = 28

Let's see if that checks out.

31-13 = 18

49 - 31 = 18

18 is not equal to 28

Since there is no common difference you cannot find the equation.

Please tell me if you made a typo and comment on my answer, then I can help you find the answer

Help pleasee<br> What is the measure of Ac?

Zina [86]

Answer:

A. 150

Step-by-step explanation:

The image shows that the measure of DE is 30 degrees, so AD must also be 30 degress. Then you just simply subtract 30 degrees from 180 degrees and you'll end up with 150 degrees. Your welcome! :)
