$12.50 is the correct answer
Applying the trigonometry ratios, the correct option is: B. none of these are correct.
<h3>What are the Trigonometry Ratios?</h3>
The trigonometry ratios are SOH CAH TOA, which are used for solving a right triangle.
Use the trigonometry ratio to find out which option is correct.
Cos Z = adj/hyp = 61/CZ, so option A is incorrect.
Sin Z = opp/hyp = 73/CZ, so option C is incorrect.
Tan Z = opp/adj = 73/61, so option D is incorrect.
Thus, the answer is: B. none of these are correct.

Answer:
x = 4 ±
Step-by-step explanation:
x² - 8x + 16 = 3 ← the left side is a perfect square
(x - 4)² = 3 ( take square root of both sides )
x - 4 = ± ( add 4 to both sides )
x = 4 ±
