c (4, 2)
parallelogram abcd has the coordinates:
find the coordinates of point d.
a) (4, 0)
b) (4, -1)
c) (3, -1)
d) (5, -2)

B)(4, -1)

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.
