Question

The vertices of a triangle are given by i+3j+2k , 2i-j+k and -i+2j+3k , then the area of the triangle is

Answer 1

Answer:

here is your answer

Explanation:

You can have the equation of line in vector form 1i+3j+2k+t(2i+1j+3k) where t is a parameter. The angle c will be the angle between vectors AC (-j-k) and BC (-2i-2j-4k) i.e. Cos(theta)=6/rt48 .theta=30 degrees.
