Terminal Ray, Unit Circle and Tangent

Question

The terminal ray of an angle drawn in standard position passes through the point(.508, .862) on the unit circle. Which of the following is closest to the tangent of this angle?

Answer 1

since the ray is on the unit circle,

the point ( .508 , .862 ) = ( cos θ , sin θ )

since tan θ = sin θ/cos θ,

tan θ = .862/.508
