What is the angle θab between a⃗ and b⃗ ? express your answer using one significant figur?

If you have to find the angle between two vectors, first of all, you should draw them with their beginnings at the common point. Then the smallest of two possible angles is the angle between these vectors (see attached diagram for details).

Now, use the definition of dot product:

Express the cosine from the previous expression:

Moreover, if   and    then

tip $2.90

total $17.40

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
