Two sides of a triangle are 10 cm and 18 cm. The third side x is an integer. How many values of x are possible?

किसी त्रिभुज की दो भुजाएं 10 cm और 18 cm हैं। तीसरी भुजा x पूर्णांक है। x के कितने मान संभव हैं?

Show answer and explanation
Correct Answer

C. 19 / 19

Explanation

The third side must be greater than 8 and less than 28 so integers from 9 to 27 give 19 values.

तीसरी भुजा 8 से अधिक और 28 से कम होगी इसलिए पूर्णांक 9 से 27 तक कुल 19 हैं।
