So basically an arithmetic sequence has a common difference, a number which is either added or subtracted at a constant rate (only that number). A geometric sequence is the ratio between two numbers, meaning they are either multiplied or divided by the same number. The sequence would be neither if it follows none of these patterns. So by this logic:

14. Arithmetic, 15. Geometric, 16. Neither, 17. Geometric

47.9 less than k is -21.6

Law Incorporation [45]

K is equal to -69.5 K=69.5 You put it in an equation 47.9-K=-21.6Then you subtract 47.9 from both sides and you get K=69.5

a parallelogram has one angle that measures 40. what are the measures of the other three angles in the parallelogram?

KonstantinChe [14]

Since one side is 40°, you subtract that from 180.

180° - 40°= 140°.

So therefore your missing side lengths are 140, 40, and 140.

hopefully this helps

Answer:

Step-by-step explanation:

<B = 360 - <A

<B = 360 - 170

<B = 190

There are two angles present, depending on which way you look at it. One is larger than 180 (the one we found) and the other is slightly less than 180 (the one you gave us).
