Answer:
10
Step-by-step explanation:
because of the math envolved
That would be 314 because 100xpi
8.) The answer would be 53.
I don't know 9 so sorry.
One way it's useful is in the application of phasors in physics. Phasors require you to add up vectors of two different angles, so the cosine angle addition formula can be used if you already know the cosine and sine of the original vector angles.
If its 2dimensional the number would be 2 because it has 2measurement hope i helped
