Liam is setting up folding chairs for a meeting. if he arranges the chairs in 9 row of the same length, he has 3 chairs left over. if he arranges the chairs in 7 rows of that same length, he has 19 left. how many chairs does liam have?

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

i think the answer is b.

step-by-step explanation:

not 100% sure though.
