Answer:
please check the explanation.
Step-by-step explanation:
Let suppose we have a number = n
- n≠0
The negative reciprocal of 'n' = -1/n
Taking the product of 'n' and its negative reciprocal '-1/n':
remove parentheses: (-a) = -a
Canceling the common factor (the number itself) will bring -1.
It proves that the multiplication of any number and its negative reciprocal will always yield -1.
I would convert to degrees first seems to make it easier.

= -468
by adding 360 twice we get the coterminal angle 252
252 is in the 3rd quadrant so 180 is the closest angle on the x-axis
ref angle = 252 - 180 = 72
If necessary convert back to radians...
