Question

Find the angle between vectors for the following. (Enter the smallest positive angle for each in degrees.)

(a)D = (−5.0î − 8.0ĵ) m and A = (−8.0î + 8.0ĵ) m

 

(b)C = (4.0î − 6.0ĵ + ) m and B = (−8.0î + 9.0ĵ + 8.0) m

 

If D = (5.00î − 3.00ĵ) m, B = (−6.00î + 4.00ĵ) m and A = (16.0î − 12.0ĵ) m, find the unknown constants a and b such that

aD + bB + A = 0.
