x = 4 units

Step-by-step explanation:

2/z = z/6

z² = 12

z = 2√3

using the Pythagorean theorem:

x² = 12 + 2²

x² = 16

x = 4

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.

1/800 is the right answer
