triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 8 cm

The right option is 8cm and 8 cm

Step-by-step explanation:

If one side of triangle is 13 then the other two sides must me greater than 13. So we will check the sum of the options one by one.

Lets take the 1st option:

5cm+8cm=13cm

It is equal to 13 but not greater than 13. So this is the wrong option.

Option 2 is:

6cm+7cm=13cm

It is also equal to 13 but not greater than 13. So this is the wrong option.

Lets see option 3:

7cm+2cm=9cm

It is less than 13. So this is the wrong option.

Option No 4 is:

8cm+8cm=16cm.

This is the right option because the sum is greater than 13
