    You can use the Pythagoras theorem, and else, where is the picture?

    Okay, then do 5^2 + 9^2 = c^2

    well there is a basic for triangles the sum of the shorter sides must be greater than the longest side... so if 9 is the longest and x is a short side you can say 5 + x > 9 if x is the longest side then 5 + 9 > x hope it helps

    a = 1st side b= 3rd side c = 3rd sides

    You can do the 3rd side has to be bigger then the other sides

    first option a = 3 b = 5 c = 9 so a +b > c 3+ 5 > 9 is it correct?

    but if you take 15, 5+9 < 15 so it doesnt work

    always any of the two sides should be equal or greater than the other
