The length of the bottom of the triangle is x. Another side is 10 more than three times the length of the bottom of the triangle. The last side is 1 more than the bottom of the triangle. plz hurry!!!​

Answer 1

`x < - 9`

Explanation:

We can only find the range of the values of x by using triangle inequality,

`x + 1 + x > 3x + 10 \\ \\ 1 - 10 > 3x - 2x \\ \\ - 9 > x`

Multiply through both sides by -1, we get,

`x < - 9`

This means x = -10, -11, ... (which is not realistic because a side of a triangle cannot be a negative number)
