Which are the possible side lengths of a triangle? 3 cm, 5 cm, 9 cm 4 cm, 8 cm, 10 cm 6 cm, 9 cm, 17 cm 8 cm, 10 cm, 18 cm

- 4 cm, 8 cm, 10 cm are the possible side lengths of a triangle.

Explanation:-

We know that in a triangle the sum of any two sides of a triangle must be greater than the third side.

Given :

1. Measurement of first triangle=3 cm, 5 cm, 9 cm

Now, for triangle Sum of two sides > third side

⇒3+5>9

⇒8>9 , which is not true.

∴ Triangle with these side lengths is not possible.

2.Measurement of second triangle=4 cm, 8 cm, 10 cm

Now, for triangle Sum of two sides > third side

⇒4+8>10⇒12>10, which is true.

⇒8+10>4⇒18>4, which is true.

⇒4+10>8⇒14>8, which is true.

∴Triangle with these side lengths is possible.

3. Measurement of third triangle=6 cm, 9 cm, 17 cm

Now, for triangle Sum of two sides > third side

⇒6+9>17⇒17>17 , which is not true.

∴Triangle with these side lengths is not possible.

4. Measurement of fourth triangle=8 cm, 10 cm, 18 cm

Now, for triangle Sum of two sides > third side

⇒8+10>18⇒18>18 , which is not true.

∴Triangle with these side lengths is not possible.

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
