Answer 6

the pythagorean theorem is \[a^{2} + b^{2} = c^{2}\] where a and b are the legs, and c is the hypotenuse
you have a=0.3, b=?, c=0.5

plug in those values and solve for b

Answer 7

So 0.2?

Answer 8

not quite...

\[(0.3)^{2} + b^{2} = (0.5)^{2}\]
\[0.09 + b^{2} = 0.25\]
\[b^{2} = 0.25 - 0.09\]
so what does b =?

Answer 9

0.4

Answer 10

much better :)
