Find the angle between vector u=2i+sqrt(11)j and v=-3i-2j to the nearest degree

Last option 155°

Step-by-step explanation:

We have the components of the vectors u and v.

Then, to find the angle between them, perform the following steps:

1) Calculate the scalar product u * v

If  and

Then, the product scalar u * v is:

2) Calculation of the magnitude of both vectors.

3) Now that you know the product point between the two vectors and the magnitude of each, then use the following formula to find an angle

answer: when you burn wood, the carbon reacts with the oxygen in the air to create ash and smoke. that is a permanent change you cannot undo that.
