Question

two vectors can be added by simple arithmetical method when they are at an angle of?​

Answer 1

Answer:

0°/180°

Explanation:

at 0 or 180 degree

the vectors are parallel or anti parallel.

so we can directly add them.

Answer 2

Answer:

Two vectors can be added arithmetically when they are at an angle of zero degrees.

Mathematical arithmetic is the study of the properties of the standard operations on numbers, such as addition, subtraction, multiplication, division, exponentiation, and root extraction.

Explanation:

When two vectors are placed side by side or are parallel to each other with no angle between them.

These two vectors can be added using simple arithmetic methods.

Now, when the vectors are anti-parallel to each other they form an angle of $180^o$.

When there are two parallel vectors, they form an angle of $0^o$.

Two vectors can be added arithmetically when they are at an angle of $0^o$.
