1. only c would work because you have to be able to take any of the two and add them and them to be GREATER than the remaining. B would be 4+2>6 which it isn't.
2. It would be A because in an equilateral triangle, each angle = 60 deg. fill that in. 60=2x+6 which ends up being
A) 27

#1 sum of two sides in less than third side and the difference in two sides is more than the third side.
4+6 < 10 and 6-4 > 2 so missing side is BETWEEN 10 and 2, therefore C is the answer.
#2 Equilateral triangle have all their angles the same size. so each angle is 60 degrees. If 2x + 6 = 60, then 2x = 54 and then X = 27. Letter A

1. The side would have to be less than 4 + 6 or 10 and greater or equal to 2
Therefore B and C would qualify
2. If the triangle is equilateral than all angles = 60°
2x + 6 = 60
2x = 64
x = 27

1) C - The third side cannot be greater than or equal to sum of the other two sides and cannot be less than or equal to the difference between the other two sides.
2) I don't know what that's asking. I don't htink you gave enough information.
