D. -3.5

C. 7

Step-by-step explanation:

took quiz on ap ex it was correct

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.

a variable is any characteristics, number, or quantity that can be measured or counted. a variable may also be called a data item. hope i !
