Two sides of a triangle have the following measures: 6, 7. Find the range of possibilities for the third side.

​ (a)   < x <​ (b)  

• 1
• 13
• 6
• 7
• 12
• 5
• 11

Two sides of a triangle have the following measures. Find the range of possibilities for the third side. (Given sides 10 and 11, the third side must be greater than the difference and less than the sum of these two sides.)

• 1 < third side < 21

• 1 ≤ third side ≤ 21

• third side > 1

• third side < 21

Two sides of a triangle have the following measures. Find the range of possibilities for the third side.

3, 8

• The third side must be greater than 5 and less than 11.

• The third side must be greater than 3 and less than 8.

• The third side must be greater than 8 and less than 11.

• The third side must be greater than 5 and less than or equal to 11.
