Answer:
i can't understant the question
Step-by-step explanation:
Answer:
Option 4
Step-by-step explanation:
The central angles are "Angles in the center"
So,
Central Angles are <AOB, <BOC and <AOC
4x -2(3x+7)
Use the distributive property:
4x - 6x -14
Combine like terms:
-2x - 14
Answer: this is rounded out, and an estimate but...
Step-by-step explanation:
It appears to be 14.03% I could be wrong, but this was calculated so maybe not.
Cos(12x) = cos(6x+6x) = cos6xcos6x -sin6xsin6x = cos^2(6x) -sin^2(6x)
1 - cos(12x) = 1 - (cos^2(6x) -sin^2(6x)) = sin^2(6x) +cos^2(6x) - cos^2(6x) +sin^2(6x) = 2sin^2(6x)
so choice A. is right sure
