side1:3 units
side2: 4 units
side 3: 6 units
Step-by-step explanation
If one angle is greater than 90° and the other two angles are lesser along with their sum being lesser than 90°, we can say that the triangle is an obtuse,so

also, if the sum of the squares of the two shorter sides of a triangle is smaller than the square of the longest side, the triangle is obtuse
so we can have the lengths.
![c^2+b^2so,let ( I choose these numbers)[tex]\begin{gathered} c=3 \\ b=4 \\ a=6 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/9c805m04qhegps00jzotu7e8v1ii51il0s.png)
now, replace to check (prove)
[tex]\begin{gathered} c^2+b^2so, the lengths are of the obtuse triangle
3, 4 and 6 units
I hope this helpsyou
