Chang knows one side of a triange is 13 cm. Which set of two sides is possible for the lengths of the other two sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm

8 cm and 9 cm

Step-by-step explanation:

In order to have a triangle, the sum of two sides must be greater than the third side.

5 + 8 = 13. That means that this will not work because the sum of the two sides is equal to 13, not greater than 13.

6 + 7 = 13. That means that this will not work because the sum of the two sides is equal to 13, not greater than 13.

7 + 2 = 9. That means that this will not work because the sum of the two sides is less than 13, not greater than 13.

8 + 9 = 17 (> 13)

8 + 13 = 21 (> 9)

9 + 13 = 22 (> 8)

That means that 8 cm and 9 cm will work because, in all three ways, the sum of two sides was greater than the third.

I hope this helps! Have a great day!

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
