Question 118759: Hello,
I am stuggling with this problem. It is highly confusing to me. Help would be appreciated as always.
~Christina-Rose~
A certain triangle has two sides with lengths 14 cm. and 29 cm.
If X represents the length of the third side, X can have a value in the range
a< x < b. What is the value of a + b ?
Note:
I got as far as 29 + 14 = 43 :(
