Answer:
the answer is an obtuse triangle
Answer:
So in your example, the odds are 7:3. In English, that means that if we had a horse race and we held 10 races with the same horses, our favored horse would finish first 7 times and lose the remaining three. But treated as a probability? If we look at it that way, we have 10 possible outcomes and the event of interest (the horse winning) happens 70% of the time. Conversely, the probability of the event not happening (the horse losing) is 30%.
Step-by-step explanation:
I believe number one is 1400
Π=180º
Cos(19π/6)=cos(19*180º/6)=cos (570º)=cos(210º+360º)=cos(210º)=
=-cos 30º=-√3 / 2≈-0.866...
Answer: cos(19π/6)=-cos 30º=-√3/2
