Answer:
median 1B: 310
Step-by-step explanation:
Answer:
75.2
Step-by-step explanation:
multiple 8 by 9.4
DE + EF = DF
x - 2 + 6x + 4 = 8x - 2
7x + 2 = 8x - 2
2 + 2 = 8x - 7x
4 = x <===
Assuming ya meant
to slimplify, we use a variation of the pythagorean identity and a decomposition into the sin and cos
for the pythaogreaon identity
divide both sides by
since
subsitute
recall that
also that cos(x) is an even function and thus cos(-x)=cos(x)
therfore
so we get
decompose them into
and
to get
multiply by
to get
we can furthur simlify to get
the expression simplifies to tan(x)sin(x)
