Answer: A x = [tex]\sqrt{2}[/tex]
Step-by-step explanation:
This is an isosceles right triangle. The two sides will have the same length, 1. The hypotenuse is calculated with the Pythagorean Theorem:
[tex]1^{2}[/tex] + [tex]1^{2}[/tex] = [tex]x^{2}[/tex]
1 + 1 = [tex]x^{2}[/tex]
x = [tex]\sqrt{2}[/tex]
