Which relation is also a function? O [(-1,3), (0, 2), (3, -1), (3, 2)}
O {(2,-4), (2,-2), (2, 1), (2,3)}
O {(0, 3), (1, 2), (1, 4), (2, 1)]}
O{(-4,-3), (0, -3), (1, -3), (4, -3)}

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.
