Question

find the angle between two vectors where A=2i and B=-6i answer in steps plz​

Answer 1

Let  a¯=2i^+3j^

b¯=6i^−4j^

taking dot product

a¯⋅b¯=(2i^+3j^)(6i^−4j^)

=12–12

=0

∵  dot product is  0∴  angle between  a¯  and  b¯  is 90 degree

Answer 2

Answer:

Let a =2i^+3j^

★5.0

b =6i^-4j^

taking dot product

a·b (2i^+3j^)(6i^-4j^)

=12-12

dot product is 0.. angle between a and bis 90 degree please mark me brain mark list
