What Expression goes with the Phrase: "The Product of 4 and the difference of 10 and b."
A. 4(b-10)
b. 4x10 -b
C. 4b- 10
d. 4(10-b)

the correct answer is 4(10 -b)

its definatley   this on your answer choice?

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.
