Answer:
C: 56,72,52
Step-by-step explanation:
we know that
An acute triangle is a triangle with three angles less than 90°
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
<u><em>Verify each case</em></u>
case A) The three measures are less than 90 degrees but the sum is not equal to 180 degrees (is not a triangle)
case B) The three measures are not less than 90 degrees
case C) The three measures represent an acute triangle ( the three measures are less than 90 degrees and the sum is equal to 180 degrees)
case D) The three measures are not less than 90 degrees. This triangle represent a right triangle

Answer:
36 times
Step-by-step explanation:
Given
![Red = 4](https://tex.z-dn.net/?f=Red%20%3D%204)
![Total = 7](https://tex.z-dn.net/?f=Total%20%3D%207)
![n = 63](https://tex.z-dn.net/?f=n%20%3D%2063)

Predicted number of times to land on red
First, we calculate the probability of landing on red
![Pr = \frac{Red}{Total}](https://tex.z-dn.net/?f=Pr%20%3D%20%5Cfrac%7BRed%7D%7BTotal%7D)
![Pr = \frac{4}{7}](https://tex.z-dn.net/?f=Pr%20%3D%20%5Cfrac%7B4%7D%7B7%7D)
The predicted number of red is the =n calculated as:
![Red = Pr * n](https://tex.z-dn.net/?f=Red%20%3D%20Pr%20%2A%20n)
![Red = \frac{4}{7}*63](https://tex.z-dn.net/?f=Red%20%3D%20%5Cfrac%7B4%7D%7B7%7D%2A63)
![Red = 4 * 9](https://tex.z-dn.net/?f=Red%20%3D%204%20%2A%209)
![Red = 36](https://tex.z-dn.net/?f=Red%20%3D%2036)
