Answer:

Step-by-step explanation:
From the question we are told that
The vector given is

Also 
Generally

Here
is the magnitude of a which is mathematically represented as

=> 
b is vector which we will assume to have the following parameters

So

=> 
=> 
Hence the vector be can be mathematically represented as

This means that the vector b is more than one value since it is made up of variable
This means that if

Then

The answer is D
Explanation- Go right 2 and and 2 for each coordinate
Answer:
x = 37
Step-by-step explanation:
Vertically opposite angles are equal
Therefore, 2x + 6 = 80
Subtract 6 from both sides: 2x = 74
Divide both sides by 2: x = 37
