Unformatted text preview: directions. We have that ( A + B ) x = A x + B x = 5.18m + 15.0m = 9.8m , and ( A + B ) y = A y + B y = 19.3m + 5.00m = 14.3m , and ( A B ) x = A x B x = 5.18m  15.0m = 20.2m , and ( A B ) y = A y B y = 19.3m  5.00m = 24.3m . So A + B = 9.8m i + 14.3m j and A B = 20.2m i + 24.3m j . Or  A + B  = [(9.8m) 2 + (14.3m) 2 ] = 17.3m and A 15.0 o A x A y B x B x B  A B  = [(20.2m) 2 + (24.3m) 2 ] = 31.6m , and 1 = tan1 (14.3m / 9.8m) = 55.6 o , and 2 = tan1 (24.3m / 20.2m) = 50.3 o . A + B = 17.3m at an angle of 55.6 o above the xaxis, and A B = 31.6m at an angle of 50.3 o above the xaxis....
