Answer: C) 65 degrees
Step-by-step explanation: the next highest is 90, but that would have the arrows in the shape of an L, since its closer than that, its lower than 90, so its 65.
Answer:
First you have to multiply negative four in parentheses, then add minus two
-4×(-8+3x)=32-12x
2+32-12x=34-12x
34-12x=82
-12x=48
x=-4
You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
The answer c, because they got 9 out of 15 flips being heads. This probability is 0.6. The other answers are not accurate.
