Respuesta :
The answer would be 7 because a triangle has 2 congruent sides and one side thatll be shorter than the other 2! Which means the other side would be 7
The rule of triangle is that any 2 sides combined must be greater than the length of the third side. This means that any number equal to or greater than 11 is incorrect. So, the only answers valid are A, B, and C. hope this helps! :)
