The distance between the points (x₁,y₁) and (x₂,y₂):
Another method:
The points have the same x-coordinate so they lie on the same line. y-coordinates are positive so you just subtract 3 from 12. See the picture in the attachment.
The answer is 9.
Apply the Law of Sines.
sinB/b = sinA/a
sinB/3 = sin(30°)/2
sinB = (3/2)sin(30°) = 0.75
Therefore
bsinA = 3*sin(30) = 1.5
0.5b = 0.5*3 = 1.5
Answer:
There is exactly one triangle because b sinA = 0.5b.
Answer:
n = 25/2
Step-by-step explanation:
First, you would want to subtract 7 from both sides of the equation. That would cancel the 7s out and 12-7 = 5. So now the equation looks like this: 2/5n = 5. Next, you would multiply both sides by 5/2, which is the reciprocal of 2/5. Now you have n= 5*(5/2). Lastly, you would just want to multiply 5*5 to get 25 and the 2 will just stay the same. So n = 25/2.
She should use the spinning wheel because its a 2/12 chance, with a wheel its a 1/6 chance.
