Answer:8.56
Step-by-step explanation:
Answer- (5x-1)(2x+1)
let me know if you need to see work
we know that
if the lines a and b are parallel lines cut by transversal f
then
--------> by alternate exterior angles
solve for x
therefore
<u>the answer is</u>
the value of x is 
9514 1404 393
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.
