[" If the vectors "(1+j+hat k)" and "3" i form two sides of a triangle,"],[" then area of triangle is: "]

If the vectors (hat(i) + hat(j) + hat(k)) and 3hat(i) form two sides of a triangle, then area of the triangle is :

If the vectors (hat(i) + hat(j) + hat(k)) and 3hat(i) form two sides of a triangle, then area of the triangle is :

The vectors 3i-2j+k,i-3j+5k and 2i+j-4k form the sides of a triangle.This triangle is

The vectors 3hat i-2hat j+hat k,hat i-3hat j+5hat k,&2hat i+hat j-4hat k form the sides of a triangle.Then triangle is

If vectors vec(A) = hat(i) + 2hat(j) + 4hat(k) and vec(B) = 5 hat(i) represent the two sides of a triangle, then the third side of the triangle can have length equal to:

The vectors 3hat i-2hat j+hat k,hat i-3hat j+5hat k and 2hat i+hat j-4hat k form the sides of a triangle.Then triangle is (A) an acute angled triangle (C) an equilateral triangle (B) an obtuse angled triangle (D) a right angled triangle

If the vectors hat i- hat j , hat j+ hat k and vec a form a triangle, then vec a may be a. - hat i- hat k b. hat i-2 hat j- hat k c. 2 hat i+ hat j+ hat k d. hat i+ hat k

If the vectors hat i- hat j , hat j+ hat k and vec a form a triangle, then vec a may be a. - hat i- hat k b. hat i-2 hat j- hat k c. 2 hat i+ hat j+ hat k d. hat i+ hat k
