Respuesta :
the sum of the lengths of any two sides of a triangle is always greater than the length of the third side
T=the third side
12+18>T
12+T>18
18+T>12
the first equation says that T<30
the second equation says that T>6
putting these together...
6<T<30
the sum of the lengths of any two sides of a triangle is always greater than the length of the third side
T=the third side 12+18>T, 12+T>18, 18+T>12, the first equation says that T<30 the second equation says that T>6 putting these together 6<T<30
