The terminal side of an angle in standard position passes through cap p times open paren 15 comma negative 8 close paren What is the value of sine theta ?

For a point (x, y) on the terminal side, sin θ = y/r, where r = √(x² + y²). Here, r = √(15² + (−8)²) = √289 = 17, so sin θ = −8/17. The correct choice is “sine theta is equal to negative 8 over 17.”
