A B C

Y

X

Point Description @X,Y

Find the relative coordinate 4 to 5. The coordinate X is
Cos 22 = X/8
X = 0.927 x 8 = 7.42
The coordinate Y is become
negative because it’s go down.
5 @7.42, -3

X

Find the relative coordinate 5 to 6. The coordinate X is
become ‘0' because it’s does not change. The
6 @0, -6
coordinate Y is become
negative because it’s go down.

Find the relative coordinate 6 to 1. The coordinate X is
become negative because it’s turn to left.
A + B + C = 7.42 + 10 + 7.42 = 24.84 @-24.84, 0 or
1
The coordinate Y is become C<enter
‘0' because it’s does not change.
