Answer:
8.81 KG (8810 g)
Step-by-step explanation:
8.1 KG (8100 g) + 710 g
So there is an identity we'll need to use to solve this:
cos(x+y) = cosxcosy - sinxsiny
replace the numerator with the right hand side of that identity and we get:
(cosxcosy - sinxsiny)/cosxsiny
Separate the numerator into 2 fractions and we get:
cosxcosycosxsiny- sinxsiny/cosxsiny
the cosx's cancel on the left fraction, the siny's cancel on the right fraction and we're left with:
cosy/siny - sinx/cosx
which simplifies to:
coty - tanx
Answer:
1.6 please correct me if im wrong by commenting
Step-by-step explanation:
Anything to the zeroth power is equal to 1. (The numerator is equal to one because of this rule)
So.
They are not equivalent, try adding in numerical values for x, both do not come out the same.
