Gracelyn has multiple sticks of different lengths to build a triangle for a class project. which 3 lengths could gracelyn choose to build the triangle?

Hello

11 cm, 25 cm, 15 cm
if you add the lengths of two sides of the triangle, it must be greater than the length of the third side

therefore, the only possible lengths are 11 cm, 25 cm, 15 cm

Have a nice day
