To determine the length of the third side of a triangle, we can use the triangle inequality theorem. According to this theorem, the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
In this case, the first two sides measure 10 and 12. So, the length of the third side must be less than the sum of these two sides, which is 22.
Therefore, the length of the third side of the triangle cannot be 24, 30, or 15.
The correct answer is 22.
Determine the length of the third side of a triangle from the choices provided if the first two sides measure 10 and 12.(1 point)
