State if the three numbers can be the measures of the ustedes of a triangle.



12, 18, 9

Remember that

The triangle inequality theorem, states that

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

so

12+9 > 18

21 > 18 -----> is true

You only need to see that the two smaller sides are greater than the largest side

therefore

the answer is

Yes, the three numbers can be the measures of the ustedes of a triangle
