Answer:
The angle = 144 degrees.
Step-by-step explanation:
Look at it this way (it is a proportion question)
30 people would require a pie chart made of a full circle (360 degrees)
12 people would require x part of the pie chart.
30/360 = 12 / x Cross multiply
30x = 360 * 12 Simplify the right
30x = 4320 Divide by 30
30x/30 = 4320/20
x = 144 Answer
The correct answers are:
______________________________________________________
[B]: " (3, -3) " ; AND:
______________________________________________________
[C]: " (-2, -3) " .
______________________________________________________
<u>
Note</u>: Any point with the "y-coordinate" of "-3" would also be on the line.
As such, the correct answers, are:
______________________________________________________
[B]: " (3, -3) " ; AND:
______________________________________________________
[C]: " (-2, -3) " .
______________________________________________________
This is the answer to your problem.
Let n = the number of points
(x-1) + ... (x-x)
The last term will always be 0, when you reach that, stop.
ex. 1pt: 1-1=0
2pt: (2-1) + (2-2) = 1
3pt: (3-1) + (3-2) + (3-3) = 3
Answer:
Not Possible
Step-by-step explanation:
This uses what is known as the triangle inequality. Basically if you add two sides the sum will be greater than the third, then if you subtract two sides it will be less than the third, keeping in mind to subtract the smaller one from the larger one.
Your sides are 7, 87 and 154
Now, I could go through each and every combination, but right away I can see 87 + 7 is less than 154, so this is not a valid triangle.
Similarly 154-7 is greater than 87 AND 154 - 87 is greater than 7, so btoh of these also mean it is not a valid triangle.
If you it doesn't make sense how I got to this conclusion I can explain.
