Answer:
4, 10
Step-by-step explanation:
The value for the third side of the triangle is given by
b-a < n < b+a where a and b are the two other sides of the triangle and b>a
7-4 < n < 7+4
3 < n < 11
Since n is an integer
4 would be the smallest value and 10 would be the largest
4/9*3/9= 12/81=4/27
You have a 4 in 27 chance of drawing a red then a blue.
7/4pi multiplied by 180/pi give you about 97 degrees when you calculate it.
