In a cross-country race with 35 participants , the mean finish time was 21 minutes . which statement must be true? a-the most common finish time was 21 minutes b-at least one participant finished in exactly 21 minutes. c-over half of the participants finished in less than 21 minutes. d-if no participants finished in less than 21 minute, than everyone finished in exactly 21 minutes

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.
