If two sides of the triangle are 4 and 7, what is the range for the third side?

To answer this question, you have to use the Pythagorean Theorem. This means a^2 +b^2 = c^2. In your problem, you have to do 4^2 + 7^2 = c^2. This turns into 16 + 49 = c^2. 16 + 49 is 65. The third side’s length is 65. Hope this helps
