Find the area of the parallelogram that has the vectors as adjacent sides. u = i+2j+2k v = i+k I know that I have to use (-2,-2,2) sqrt (1-2)^2 + (2+2)^2 + (2-2)^2 = sqrt17 Area = sqrt 17. Is this correct?

Find the angle Q between the two vectors. u = 10i + 40j v = -3j+8k cos <10,40,0> <0,-3,8> / sqrt1700 sqrt73 cos(-120/sqrt1700 sqrt73) = .9072885394 arc cos (.9072885394) = 24.86 degrees. Is this correct?
