A triangle has side lengths of 2 cm, 8 cm, and x cm. Which measure could be the value of x in centimeters?

A. 6

B. 9

C. 10

D. 12

9

Step-by-step explanation:

Since, the sum of lengths of any two sides in a triangle should be greater than the length of the third side.

It is given that two sides of triangle are 2cm and 8cm.

Therefore, the third side should be less than 2+8=10cm.

And also the third side cannot be less than the difference of the two sides.

Therefore, the third side has to be more than 8-2=6cm

Therefore, the third side should be the length more than 6cm and less than 10cm.

therefore, 6cm< 3rd side <10cm
