1. Carlito is observing an ant that crawled along a tabletop. With piece of chalk, he followed
its path. He determined the ant's displacements by using a ruler and protractor. The
displacements were as follows: d= 2 cm east; d= 3.5 cm, 32° north of east; and d= 2.3 cm,
22° west of north. Using parallelogram method, determine the resultant vector by (d+ d) +
d.
