(c) (-12/13, -5/13)
(d) (12/13, 5/13)
Step-by-step explanation:

__
(b) The terminal point is effectively reflected across the x-axis, so the sign of the y-coordinate changes. (12/13, -5/13)
__
(c) The terminal point is effectively reflected across the origin, so the signs of both coordinates change. (-12/13, -5/13)
__
(d) The terminal point is mapped to itself, so its coordinates remain unchanged. (12/13, 5/13)

Step-by-step explanation:
You need to use a Z-table for this.
There are different tables, in this table i searched for the probability of 97% because that equivalent to the top 3%.
for 0.97, Z = 1.88
The formula of Z is:
Solving x:
