1. (10 points) ( Average Power and Power Factor) (a) (5 points) Find the average power, Pav, given v(t) = 8 cos(754t - 309)V, and no' i(t) = 0.2

I'm confused how to solve the question so maybe you can guide me through the steps

1. (10 points) ( Average Power and Power Factor)(a) (5 points) Find the average power, Pav, given v(t) = 8 cos(754t - 309)V, andno' i(t) =0.2 sin(754t) A.(b) (5 points) How far in time is i(t) shifted relative to v(t)? (*Hint* Consider the unitsof $z and w.)
