If p(x, y) is the point on the unit circle defined by real number theta, then tan theta= a. x/y b. y/x c. 1/x d. 1/y

Option B is correct.    

Step-by-step explanation:

We have been given a point  on unit circle  defined by real number theta.

So, tan theta is the given by:

Equation of unit circle is

Where 1 is the radius.

Therefore, Option B is correct that is

10% of increase is the final answer! : )
