To determine the length of the third side of the triangle, we can use the triangle inequality theorem.
According to the theorem, in a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Therefore, in this case, the sum of the first two sides (10 and 12) is 22.
If the third side is 15, then the sum of the first two sides (10 and 12) would be equal to the third side (15), which would not satisfy the triangle inequality theorem.
Therefore, the length of the third side of the triangle from the choices provided below is 22.
Determen the length of the third side of a triangle from the choicses provided below if the first two sides measure 10 and 12
is it 15 or 22
