Answer:
Step-by-step explanation:
tan47=x/18
x=18tan47
cosCDB=7/x
cosCDB=7/(18tan47)
CDB=arccos(7/(18tan47))
CDB=68.74
lol, that would be biology
but I'd say its the mitochondria
save more has a better deal because when you convert 33% into a fraction out of ten it becomes 3.3/10 and shop right is 3/10 so 3.3 is greater than 3.
Answer:
Step-by-step explanation:
f(4) = 4-7 = -3
g(-3) = (-3)^2 = 9
Since you have two numbers that have a (x) at the ends of them, you add those first then add seven which will end up being 9x+7
