Question

If 2 sides of a triangle are 10 and 20, what is the possible range of the 3rd side?

Answer 1

Answer: 10<x<30

Step-by-step explanation: The third side of the triangle has to be greater than the difference of the other two sides and smaller than the sum of the other two sides.

Answer 2

Answer:10<x<30

Explanation:

According to the triangle side theorem all you need to do is this.

Difference of the two sides<x<Sum of the two sides.

That will give you the range your looking for. For the difference always remove the smaller number from the bigger number so you can always have positive integers.
