What is the sum of the following four vectors in unit-vector notation? For that sum, what are (b) the magnitude, (c) the angle in degrees, and (d) the angle in radians? Positive angles are counterclockwise from the positive direction of the x axis; negative angles are clockwise. vector E - 6.00 m at +0.9 radians
vector F - 5.00 m at -75 degrees
vector G - 4.00 m at 1.20 radiansvector H - 6.00 m at -210 degrees
