Answer:

10.3

Step-by-step explanation:

Pythagorean Theorem:

[tex]a^{2} + b^{2} = c^{2} \\[/tex]

a and b being the sides and c being the hypotenuse.

[tex]3.9^{2} + b^{2} = 11^{2}[/tex]

15.21 + [tex]b^{2}[/tex] = 121

[tex]b^{2}[/tex] = 121 - 15.21

[tex]b^{2}[/tex] = 105.79

b = [tex]\sqrt{105.79}[/tex]

b = 10.3
