1. replace ? with a whole number to make the statements true.
a. 20+4 ? means ? x 4 = 20
b.2.725 + 5 ? means ? x 5 = 2.725
c. ? = 5= 0

A. 6

B. 0.545

C.25/5=5/5=0

Step-by-step explanation:

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.
