Step-by-step explanation:

Answer:

The function value.of cos (-305.3)° is 0.5921

Step-by-step explanation:

To find the value of cos (-305.3)°, we can use the periodicity property of the cosine function. Since cos (x) is a periodic function with a period of 360 degrees, we can add or subtract multiples of 360 degrees from the angle without changing the value of the cosine.

Step 1: Convert -305.3° to an equivalent angle within period one (0 to 360 degrees).

-305.3° + 360° = 54.7°

Step 2: Calculate the cosine of the equivalent angle.

cos (54.7°)

Step 3: Use a scientific calculator or trigonometric table to find the cosine value.

cos (54.7°) ≈ 0.5921

Therefore, the value of cos(-305.3)° is approximately 0.5921
