Question 391065: I'm studying for the GED and I really need help with this question. If two sides of a triangle are 6.5 and 8.5 inches long, which of the following cannot be the length of the third side? A. 5.5 inches, B. 6.5 inches, C. 9.5 inches, D. 12 inches, and E. 15 inches. How do you figure it out? Answer by solver91311(24713) (Show Source):
Use the triangle inequality. In order to have a triangle, the sum of any two sides must be strictly greater than the third side. Add 6.5 to 8.5. The third side must be strictly less than that sum.
