Answer:
yes I'm pretty sure your answer would be correct if you got D

Answer:
Step-by-step explanation:
You can calculate the length of side a using the Cosine Rule:
a^2 = 32.6^2 + 41.4^2 - 2.32.6.42.4 cos pi/6
a^2 = 456.01
a = √456.01
a = 21.35
By the Sine Rule:
32.6 / sin B = 21.35 / sin pi/6
sin B = (32.6 * sin pi/6) / 21.35
sin B = 0.76347
B = 0.869 radians.
C = pi - pi/6 - 0.869 = 1.749 radians.
The correct answer is
D) 1/2
because
5/10 = 1/2

1 4 0 We've got the same difference before. That means numbers will be repeated.
So:
25:405 = 0.0 6 1 7 2 5 9 2 (3 4 5 6 7 9 0 1 2)
26 possible letters
assuming you can repeat them
26*26*26
no listed
ok, lets assume that you can't repeat them
that is 26 times 25 times 24 (because you used 1 each time)
that is 26!/23! (because 26*25*24*23!=26!)
answer is D (only if there is a factorial sign after the 23)
