What is the sum of the following four vectors in (a) unit-vector notation, and as (b) a magnitude and (c) an angle? Positive angles are counterclockwise from the positive direction of the x axis; negative angles are clockwise. = 4.00 m, at 65.0° = 5.00 m, at -235°

The angle will be "124°". The further explanation is given below.

Explanation:

As we know,

(a)...

Let the resultant of , , and will be , then

⇒  

On putting values, we get

⇒      

⇒      

(b)...

On squaring both sides, we get

⇒  

⇒      

(c)...

Let the resultant angle will be "",

⇒  

⇒  

⇒  

the answer is to check all of them! they all apply well at least i think so!
