What is the value of cosθ given that (−2, 9) is a point on the terminal side of θ ? 985√85 −985√85 285√85 −285√85​

r = √ [ x^2 + y^2 ] = √ [ ( -2)^2 + 9^2 ] = √85

r = √ [ x^2 + y^2 ] = √ [ ( -2)^2 + 9^2 ] = √85

r = √ [ x^2 + y^2 ] = √ [ ( -2)^2 + 9^2 ] = √85 cos θ = -2 / √85 = -2√85 / 85

r = √ [ x^2 + y^2 ] = √ [ ( -2)^2 + 9^2 ] = √85 cos θ = -2 / √85 = -2√85 / 85

-2√85√85
