For a right triangle ABC, you are told that cos A = x and sin A = y. Which option below gives an expression that is equivalent t o tan A? a. x/y b. y/x c. x/√x^2+y^2 d. y/√x^2+y^2

Draw a right triangle ABC so that m∠C = 90° The lengths are: Side a is opposite ∠A, Side b is opposite ∠B, Side c (the hypotenuse) is opposite ∠C Because cos A = x, therefore x = b/c => b = cx (1) Because sin A = y, therefore y = a/c => a = cy (2) By definition, tan A = a/b = (cy)/(cx) = y/x Answer: b. y/x
