Exam task, Determine the height of the triangle.

• Determine the height h of triangle ABC, if A(-1,0,1), B(0,2,-3),C(4,4,1).

Given formulas for solving in the command window:

P=0.5*|BAxBC|

P=(BC*h)/2

• I'm a beginner.

The focus of my problem is how to vector multiply the vectors BA and BC, and if someone can, I would be grateful for the solution.

(I know the formula for the value of the vector product, but I don't know the angle to use it)

It may seem easy, but I've been struggling for a long time (4 hours). I tried to check the solution by using the scalar product property (the scalar product of base BC and height is =0) but I don't get 0
