Answer:
-2/3
Step-by-step explanation:
The slope of a line perpendicular to one with a slope of 3/2 will have a slope that is the negative reciprocal of that:
red slope = -1/(3/2) = -2/3
Using the fact that cos is 2π-periodic, we have
That is, for any and integer .
We get 2 solutions in the interval [0, 2π] for and ,
