Question

Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options.

Answer 1

16 < n < 40

Explanation:

use triangle inequality theorem:

n = length of third side

12 + 28 > n; n > 40

12 + n > 28; n > 16

n + 28 > 12 (this inequality can be discounted because it results in a negative)
