A scalene triangle ABC has two sides whose measures are 3.8 cm and 6 cm, respectively. Which of the following CANNOT be the measure (in cm) of its third side?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2.2.
For a triangle to be formed, the sum of any two sides must be greater than the third side.
We have two sides: 3.8 cm and 6 cm.
2.2 can't be the 3rd side of the triangle because 2.2 + 3.8 = 6.
