1. if the point p(-4/5, y) lies on the unit circle and p is in the third quadrant, what is y? explain. 2. if the point p(x, 2/3) lies on the unit circle and p is in the second quadrant, what is x? explain.

1.

2.

Step-by-step explanation:

Ques 1: We are given that the point lies on a unit circle and is in the 3rd quadrant.

The equation of the unit circle is .

Substituting the values, we get,

⇒

⇒

⇒

⇒

⇒

⇒

Since, the point P lies in the 3rd quadrant i.e. the value of y will be negative.

So, .

Ques 2: We are given that the point lies on a unit circle and is in the 2nd quadrant.

The equation of the unit circle is .

Substituting the values, we get,

⇒

⇒

⇒

⇒

⇒

⇒

Since, the point P lies in the 2nd quadrant i.e. the value of x will be negative.

So,

answer: idk
