Find all values of x so that the triangle with vertices A=(−4, −3, x), B=(−7, 0, 5), and C=(−1, −6, 8) has a right angle at A.

Answer 1

Hello, can you help me with this question?

Answer 2

i need help. On im doing a 5 column chart for social studies. If u look on newest and u see social studies that may be mine the name is still the same

Answer 3

as with the other question just like this one, you want AB•AC = 0
So,
A=(−4, −3, x), B=(−7, 0, 5), and C=(−1, −6, 8)
(-7+4)(-1+4) + (0+3)(-6+3) + (5-x)(8-x) = 0
x = 2 or 11
