Answer:
BC = 8 units
Step-by-step explanation:
Mistake lies in the Step 1:
Since, 10 is the length of hypotenuse and 6 is length of one of its leg.
[tex] \therefore 6^2 +10^2 \neq BC^2 [/tex]
The length of BC can be given as:
[tex] \therefore 6^2 +BC^2 = 10^2 \\
BC^2 = 10^2 - 6^2 \\
BC^2 =100-36\\
BC^2 = 64\\
BC =\pm\sqrt{64}\\
BC = 8 \: units
[/tex]
