Final answer:
The correct expression to solve for z is likely 'z=8tan22°' as options A and D are identical, suggesting that z is equal to 8 times the tangent of 22 degrees.
Step-by-step explanation:
To find the correct expression to solve for z, we need to know the relationship between z and other given variables or functions. Without additional context, it is hard to determine the relevant equation. However, since only one option in the multiple-choice question can be correct and options A and D are identical, we can infer that z=8tan22° is likely correct. Nevertheless, always ensure to have the proper context or equation related to the problem at hand.
