Question

A triangle has one side that measures 12 inches and another side that measures 33 inches. Which are possible side lengths of the third side?

Answer 1

Greater than 21

Less than 45

Explanation:

You add and subtract the two numbers you are given.

33 - 12 = 21

The third side has to be bigger than 21.

33 + 12 = 45

The third side has to be less than 45.

It can be written in one math sentence:

21 < x < 45
