It can be any length greater than 7 and less than 17.

OpenStudy (anonymous):

so c

OpenStudy (anonymous):

12-5 = 7, 12+5 = 17, the answer is c

OpenStudy (anonymous):

@ErinWeeks u get it??

OpenStudy (anonymous):

@ErinWeeks : It has to be C .. *Sum of two sides of a triangle, must be greater than the third side.* Thw inequality 7<x<17, satisfies this condition.

OpenStudy (erinweeks):
