Two sides of a triangle have lengths 8 ſt and 12 ſt.
describe the possible lengths of the third side.

4<x<20

Step-by-step explanation:

the missing side must be between these two values because it is the difference of 8 and 12 and the sum of 8 and 12. we do this calculate because to make a triangle, any two sides must add up to be greater than the third side. so it can't be 4 because 8+4= 12 and the sides can't be equal (must be greater) and it can't be 20 because 8+12 = 20 and they can't be equal. so it must be anywhere between 4 and 20.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.
