The point P is on the unit circle. Find P(x, y) from the given information. The x-coordinate of P is 12/13 , and the y-coordinate is negative.

Answer 1

(12/13,-5/13)

x^2 + y^2 = 1

(12/13)^2 + (-5/13)^2 = 144/169 + 25/169 = 169/169 = 1

It's a similar right triangle with sides -5 and 12, with hypotenuse 13

5^2 + 12^2 = 13^2
