Now what do you do if there are variable expressions for the side lengths? This video explains that type of problem...check it out here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-RZkOM7jWf7o.html

@tarrumii1536 6 лет назад

So that's how you would find the range of the length for the third side? What would my answer be if my two sides are 9 and 15? If I subtract and add them I would get 6 for subtracting and 24 for adding. Would this be my range?

@MariosMathTutoring 6 лет назад

+Last Hope yes that is correct...you got it...it would be greater than but not equal to 9 and less then but not equal to 24.
