1. 2. A Vector Bb is 1 inch long and has a direction - sense of 45 deg. Vectore Cc is 1 inch long and has a direction of 150 degrees. Find the Vector Sum. Given Five vectors whose lengths and dirction - senses are as follows: Aa is 1.5 inch long and 90 degrees, Aa2 is 1.25 inch long and 315 degrees, Aa3 is 2 inches long and 0 degrees; Aa4 is 1.25 inch long and 225 degrees; Aa5 is 1.5 inch long and 45 degrees. Find the vector sum of the first four and subtract Aa5 from the resultant vector.
