Given vector A has a magnitude of 15 meters directed 27 degrees above the positive x-axis, and vector B has a magnitude of 22 meters directed 18 degrees above the positive x-axis, calculate A · B . A.
313.9 m^2

B.
325.9 m^2

C.
330.0 m^2

D.
294.0 m^2

there are no correct statementd on the list of choices you provided.

the answer is b

explanation:

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

this would be about 43%
