Determine the length of the third side of a triangle from the choices provided if the first two sides measure 10 and 12 answer choices. 15,22,30,24

The length of the third side of a triangle must be greater than the difference of the other two sides but less than the sum of the other two sides.

10 + 12 = 22
12 - 10 = 2

Therefore, the possible range for the third side is 2 < x < 22.

From the answer choices provided, the only length that falls within this range is 15.

Therefore, the length of the third side of the triangle is 15.
