Is this correct? A triangle has the following measurements. What is a possible length for the third side? AB = 4, BC = 17, CA = ? A. 5 B. 10 C. 12 D. 18 I think the answer is D.18, is that right?

well, im new into this but I know that the sum of two sides of a triangle is always greater than the third side and the difference of two sides of a triangle is always smaller than the third side, and that the third side lies between 13 and 21. that's how I got the answer...
