Which is one reason why this expression is equal to 0? math item stem image clear check the product of any number and its opposite is 0. the expression does not equal 0. the sum of any number and its opposite is 0. the same number appears in the numerator and denominator.

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.
