Answer 3

Now:
\[a^2+b^2=c^2 \]

Answer 4

\[6^2+b^2=12^2\]

Answer 5

oh so to find the altitude is b right?

Answer 6

Correct. :o)

Answer 7

isnt the answer like 10.39?

Answer 8

Yup, or you could round it to just 10.4 :o)

Answer 9

For the next one, do you mean:\[7\sqrt{2}\]

Answer 10

\[a^2+b^2=c^2\]
\[7\sqrt{2}^2+7\sqrt{2}^2=c^2\]\[7\sqrt{2}^2 = 14\]\[14+14=28\]
