Over here, we have a 45-45-90 special right triangle.
According to base angle theorem converse, this triangle is a congruent triangle so x = 14.
In a 45-45-90 triangle, the hypotenuse is the leg multiplied by [tex]\sqrt{2}[/tex]
So it would be:
14[tex]\sqrt{2\\}[/tex]
Hope this helps, let me know if you have any questions since it wasn't the best explanation.
