The figure represents a abcd irregular quadrilateral. determine the coords of the vector ap knowing: the points a, b, c, d, e, p belongs to the same plane ad = [2 2 -2] bc = [2 4 1] ||ap|| = ap is ortogonal to bc line the ap abscissa is negative

There may be an easier way, but this is a way I know will work.

The vectors AD and BC are both in the same plane, so that plane will have a normal that is in the direction of their cross product.

... AD × BC = [10 -6 4], which can be reduced to [5 -3 2]

Since AP ⊥ BC also lies in the same plane, it will be orthogonal to [5 -3 2] and to [2 4 1], so its direction can be found from the cross product of these vectors.

... [5 -3 2] × [2 4 1] = [-11 -1 26]

Now all we need to do is to find the factor this needs to be multiplied by to get the desired magnitude.

||[-11 -1 26]|| = √798, so our multiplying factor is (√6)/3/√798 = (√133)/399

Then the coordinates of P are [-11√133/399 -√133/399 26√133/399]

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

da freeck kinda math is this just drop out
