Answer:
don't know
Step-by-step explanation:
Seems to be an arythmetic sequence
Sn=[n(a1+an)]/2
where
Sn means sum of all terms up the nth term
n=number of terms
a1=first term
an=nth term
so from 86 to the 22th term is from a1 to a22
find teh sequence
miknus 7 each time
an=a1+d(n-1)
an=87-7(n-1)
find 22n term
a22=87-7(22-1)
a22=87-7(21)
a22=87-147
a22=-60
S22=[22(87-60)]/2
S22=[22(27)]/2
S22=594/2
S22=297
the sum is 297
Answer:
d and b
Step-by-step explanation:
Answer:
This is not my answer, it was done by another expert in Brainly.
We are given:
csc (0) * sin (0)
This is to be simplified using trigonometric identities:
csc (x) = 1/sin(x)
so, csc (0) = 1/sin(0)
then,
1/sin(0) * sin (0), the result will be sin(0) / sin (0) which is equal to 1.
Therefore, the answer is 1.
