Positive angles are counterclockwise from the positive direction of t the x axis; negative angles are dockwise A = 12.00 m), + 13.00m) = 4.00 m, at 65.00 C-4.00 m li- (6.00 m 5.00 m, at-2350 (b) Numbe unit (c) NumberUit Answer 1: the tolerance is +1.2% Answer *2: the tolerance is +1.2% Answer *3: the tolerance is +/-2% Answer *4: the tolerance is +/-296 Quest Type here to search

Explanation / Answer

here,

B = 4 * ( cos(40) i + sin(40) j) m

B = 3.1 i m + 2.57 j m

sum of these vectors , S = - 3.172 m i + 4.71 m j

c)

angle , theta = arctan(4.71/(-3.172))

theta = 124 degree counterclockwise from +x axis
