Answer:
[A] use the complementary relationship between sine and cosine to rewrite sin(x + y) as cos(pi/2-(x+y)). apply the cosine sum identity. then simplify using sin(–y) = –sin(y) and cos(–y) = cos(y).
Step-by-step explanation:
i got it right
screw that other person l0l
note that sin(-x)=-sin(x) and cos(-x)=cos(x)
so sin(-y)=-sin(y) and cos(-y)=cos(y)
or something like that idfk
Answer:
The answer is "
".
Step-by-step explanation:
In the question the total given value =4(x+7). if we add the value it will be 11 but if we multiply the value it is equal to .
Answer:
78cm
Step-by-step explanation:
780mm = 780/1000 (m)
therefore 780mm = 0.78 m
but 100cm = 1m
implying that
0.78m = 78cm
Answer: x = 3.6 Thats the answer.
