Question

check whether the vectors A and B are parallel or perpendiclar if A= i + J + K and B= -i - j+2k​

Answer 1

Angle was 90 degree,..,.,,, I think u find the angle

Answer 2

Answer:

perpendicular

Explanation:

A= i + j + k

B=-i-j+2k

vector A.vectorB=1.(-1)+1.(-1)+1.(2)

= -1 -1 +2

=0

Vector A is perpendicular to Vector B.

i. e. angle between vector A and vector B is 90 degree.
