Given:
A plane is normal to the vector = -2i+5j+k
It contains the point (-10,7,5).
To find:
The component equation of the plane.
Solution:
The equation of plane is

Where,
is the point on the plane and
is normal vector.
Normal vector is -2i+5j+k and plane passes through (-10,7,5). So, the equation of the plane is





Therefore, the equation of the plane is
.
Answer:
the same way Pythagoras Theorem
and sorry for the hand writing
Answer:
I cant give you an answer but hints:
First you gotta know the angles of the triangle
then how many are there
then those lines in the middle is dividing lines so
right angles are 90 degrees
I would go for B then.
if not I'm sorry
