Aaron is interested in biking because his friends ride a lot. He doesn’t want to spend a lot of money on his first good bike because he is not sure how much he
will like riding. Aaron figures he can always upgrade if he enjoys the sport. He
went to the bike shop and found their prices to be expensive for a beginner. Does
he have to pay retail to get a good bike? Explain

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser

step-by-step explanation:

this answer is !

arc length = radius * x ( in radians)

6 * pi = 18 * x

divide by 18 on each side

6 pi / 18 = x

pi/3 = x

the angle is pi / 3 radians

or   60 degrees
