Answer:
56.
Step-by-step explanation:
That is the number of permutations of 2 from 8
= 8P2
= 8!/(8-2)!
= 8!/6!
= 8 * 7
= 56.
(-3,1)
x,y > -y,-x
Therefore (-1,3) is (-3,1)
Answer:
2(
+8x+17)
Step-by-step explanation:
Factor out 2 of the equation.
As the sine rule states,
A/sina = B/sinb = C/sinc .
in the diagram, there are two identified sides and if you use the sine rule, you can find the opposed angles easily.
there are:
side a, with angle â .
side b, with angle b.
so the answer is C.
if you input these into the sine rule, it would be:
a/ sin a = b/sin b
It would be 250/1000 or 1/4
