Ok so I am gonna help you with this question I hope it helps you okay!
Answer:
i think it 77 hope this helps
17.09090909... Just divide 188 by 11
The slope is -999’inc because yssjjdidijdnxjdnxnnxkxkx
Step-by-step explanation:
½ [cos(a − b) − cos(a + b)]
Using sum and difference formulas:
½ [cos a cos b + sin a sin b − (cos a cos b − sin a sin b)]
Distribute the negative:
½ (cos a cos b + sin a sin b − cos a cos b + sin a sin b)
Combine like terms:
½ (2 sin a sin b)
Simplify:
sin a sin b
