Question

find the area of a triangle OABsuch that vector OA = ICAP + 2 J cap + 3 k cap and vector OB = - 3 ICAP - 2 J cap + K cap ​

Answer 1

Answer:

I can find perimeter because which triangle it is forming

oh. mate we can find perimeter only if OA and OB are in same order

how I know that they they are in same order. for that u have to see send photos alongside ok

ok ... if they are in same order then

here is ur answer .

no bro. how u know the value of the angle between OA and OB

I think u have to repost the question again with the mention theta , and how the triangle is forming whether it is which triangle.
