Write the vector u as a sum of two orthogonal vectors, one of which is the vector projection of u onto v, projvu u=(-9,3), v=(-9,3)

  u = v

Step-by-step explanation:

Vector u appears to be the same as v, so its decomposition is simply ...

  u = projvu = v

__

There is no orthogonal component.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
