Question

A triangle has two sides of length 7 and 10. What is the largest possible whole-number length for the third side?

Answer 1

16 units.

------------------

According to triangle inequality theorem, any side of a triangle is less than the sum of the other two.

Let the missing side is largest, then it must be less than:

• 7 + 10 = 17

The closest whole number less than 17 is 16.
