Given a triangle with side lengths of 20 cm and 7 cm, what is a possible length of the third side?

A. 13 cm

B. 14 cm

C. 27 cm

D. 28 cm

Answer 1

B. 14

Explanation:

To determine whether a triangle or not, use the triangle inequality theorem. Two smaller sides must add up and be greater than the larger side.

13+7=20 wouldn't work

14+7>20 would work

7+20=27 wouldn't work

7+20<28 wouldn't work
