Yes, D is correct as long as the 8 is a 6. Was the 8 supposed to be a 6 instead?
No it says 8.
I agree with Brady. The correct answer is 10.6.
Thanks
Well, it is still correct, even though when solved, it would be closer to 10.6 as the approximate value.
a^2 + b^2 = c^2
7^2 + 8^2 = c^2
49 + 64 = c^2
113 = c^2
10.630145812734649407999121914929 = c
10.630145812734649407999121914929 is closer to 10.6, but in this case 10.8 is correct.
I hope this helps! :)

it is 10.6 not 10.8
How did you get the 10.6 Brady?
