Vector a has a magnitude of 16 m and makes an angle of 44° with the positive x axis. vector b also has a magnitude of 13 m and is directed along the negative x axis. find a+b (in meters and degrees)
find a-b (in meters and degrees)

Answer with explanation:

The given vectors in are reduced to their componednt form as shown

For vector A it can be written as

Similarly vector B can be written as

Hence The sum and difference is calculated as

The direction is given by

with positive x axis.

Similarly

The direction is given by

with positive x axis.

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
