Answer

Final Answer: $\frac{4 \sqrt{5}}{9}$

Steps

Step 1 ：To find the value of $\cos (- t)$ , we need to remember that the cosine function is an even function, which means that $\cos (- t) = \cos (t)$ .

Step 2 ：Since we are given that $\cos t = \frac{4 \sqrt{5}}{9}$ , we can directly use this value for $\cos (- t)$ .

Step 3 ： $\cos (- t) = \frac{4 \sqrt{5}}{9}$

Step 4 ：Final Answer: $\frac{4 \sqrt{5}}{9}$
