Answer:
90° CCW
Step-by-step explanation:
The slope of BA is -1/3. The slope of BA' is 3, so the slopes are opposite reciprocals of one another. These segments are perpendicular, meaning the angle between them is 90°.
Point A' has been rotated 90° CCW about point B.
Answer:
the answer would be 12 I think.
Step-by-step explanation:
X^2+6x=7X^2
If he uses 85 tiles, 28 tiles will be black
<h3>Sequence and Pattern</h3>
The formation of the tiles of the floor follows an arithmetic sequence or pattern
The pattern is given as:
<h3>Formation of the tiles</h3>
Given that the total number of tile used is 85, and the black tile is always in the third position.
The highest number less than or equal to 85 that is divisible by 3 is 84.
Next, we divide 84 by 4


Hence, 28 of the tiles will be black
