I don’t have a very detailed explanation, however the answer should be “A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left”.
You can clearly see a 90° angle here, it’s obvious. Also, the polygon switch counterclockwise. so, you can see.
hope I helped ^^
Angle PTG = arccos((18^2 + 13^2 - 27^2) / (2 x 18 x 13)) = arccos(-236 / 468) = arccos(-0.5043) = 120 degrees.
The triangle is an obtuse triangle (because one of the angles is greater than 90 degrees) and a scalene triangle (because all the sides are not equal).

Answer:
Step-by-step explanation:
Let m represent the number of months since joining the newspaper.
Let a represent the total number of articles he has published.
The columnist had already published 46 articles before joining a newspaper. Since then, he has published 11 more articles every month. This means that in m months, the total number of articles he would have published is
a = 46 + 11m
Therefore, when m = 6,
a = 46 + 11 × 6 = 46 + 66
a = 112
