Homework Statement
Triangle ABC formed by two vectors a = ( 2, 10, 25 ) and b = ( 5, 4, -2 ) attached at a point A.
The area of the triangle is (81 root 5) / 2
And I need to find the length of the height AM (AM perpendicular to BC and the point M belongs to the line BC).
Don't know where to...
Thanks..I thought I was on the right lines, just needed reassuring :)
I got the area of the traingle to be 81root5 / 2
But now I need to calculate the length of the height PM (where PM perpendicular to BC and the point M belongs to the line BC)
I'm guessing as I know the area and 2...
