Once at the posted coordinates you will observe some benches.
A = the number of benches.
B = the total number of metal posts holding up all the benches.
To determine the final coordinates do a projection from posted using the following:
meters = (77 x A)
angle = (76 x B)
To ensure you have the correct answers for the above the sum of the angle and meters is 458.
The last digit of the north coordinates is 0 and the last digit in the west coordinates is 6.
