Answer:

6.6 yd

Step-by-step explanation:

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

[tex]10^{2}[/tex]+[tex]b^{2}[/tex]=[tex]12^{2}[/tex]        Substitute a= 10 and c=12

100+[tex]b^{2}[/tex]=144      Evaluate the Powers

[tex]b^{2}[/tex]=44               Subtract 100 on both sides.

b=[tex]\sqrt{44}[/tex]             Square root both sides b>0 so you dont need ⊥

b=6.6              Use a calculator to evaluate.
