Select the correct answer. Triangle XYZ has an altitude of h. Jayden proves the area of AXYZ using trigonometry. His work is shown. Y h b a y The area of AXYZ is Zyh by the definition of the area of a triangle. Using the sine ratio, 81n(X) = 7. Also, *3in(X) = h is true by the multiplication property of equality. So, by the substitution property of equality, the area of AXYZ is Where did Jayden make his first error in the proof? O A. The area of AXYZ İs incorrect. It should be ah. OB. The sine ratio sin(X) = is incorrect. It should be sin(Y) = . Oc. The area of AXYZ İs incorrect. It should be O D. The sine ratio sin(X) = is incorrect. It should be gin(Z) =
