Question

Can you make a triangle with side lengths of 7, 8 , and 15?

A. Yes, because 7 + 8 is not less than 15

B. Yes, because 7 + 8 is not greater than 15

C. No, because 7 + 8 is not greater than 15

D. No, because 7 + 8 is not less than 15

Answer 1

Note that 7 and 8 add up to 15.  If the third side were of length 15, all of the sides would be congruent with the same straight line, thus not really creating a triangle.  Given this reality, which of the above answers sounds most reasonable?

Answer 2

It is C ************************************
