The reciprocal is the flipped value so it will be11/9
Answer:
The first one is right the rest of them is not right correct
Step-by-step explanation:
Here we are supposed to find the distance between the two points
Suppose A=(-8,-9), B=(-4,-10)
Now As per the distance formula we know that the distance between two points is given by the formula

The complete question in the attached figure
we know that
sin40° = opposite side / hypotenuse
opposite side =AC
hypotenuse = AB-------> 10 in
so
sin 40=AC/AB---------> AC=AB*sin 40-------> AC=10*sin 40
the answer is
AC=10*sin 40
Your answer would be c. 18,6
