Hiya! 20 points! What rotation was applied to triangle DEF to create triangle D′E′F′?

90° counterclockwise
90° clockwise
None of the above
180°

Hewo!

180 degrees

If it was 90 degrees it would be the same thing just fliped. 180 means that it did a half a rotation so it would be the mirrored of the original object. That is what we see the second figure is mirrored of the other. 90 degrees also would be different.

90 counterclockwise

Step-by-step explanation:

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
