Two sides of a triangle have lengths 9 and 15. What must be true about the length of the third side? a. less than 9 b. less than 6 c. less than 15 d. less than 24

OpenStudy (erak):

I believe it's d, it must be less than 24. I'm not completely sure how to explain it, but if your angle between those two were as close to 180° as possible, you would get under 24
