Need help on this to!! thanks <33

4) n = 12

5) n = 2.5

Step-by-step explanation:

4) 45/4 = 11.25

135/11.25 = 12

5) 2/1 = 2

5/2 = 2.5

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.
