Question

The lengths of two sides of a triangle are 11 cm and 19 cm. Identify the range of possible lengths for the third side. a. 12 cm < x < 30 cm b. 8 cm < x < 30 cm c. 8 cm < x < 31 cm d. 11 cm < x < 19 cm

Answer 1

The correct option is B

Explanation:

The sum of two sides must be bigger than the third side and the difference of two sides must be smaller than the third side :

So,

19 - 11 < x < 19 + 11

8 < x < 30
