Answer:
(√6 - √2) / 4
Step-by-step explanation:
cos(x+y) = cosx siny - sinx cosy
cos(75°) = cos(30°+45°) = cos30° sin45° -sin30°cos45°
= √3/2 * √2/2 - 1/2 * √2/2
=(√6 - √2) / 4
If this question has the same set of choices to the previous ones, the answer to the question presented above is letter A. 3 ÷ 7.3 over seven means 3 divided by 7. Choices to the question presented above are the following:A. 3 ÷ 7 B. 3 × 7 C. 7 ÷ 3 D. 7 × 3?

Step-by-step explanation:
Given x < 5
The graph will have an open circle at 5 indicating that x is not equal to 5, which would be a closed circle.
The ray will move to the left since values less than 5 are to the left of 5
