do you know about pythagoras theorem?

Answer 5

no I want but I think I heard it some were

Answer 6

but I can look it up real quick

Answer 7

In a right triangle with legs, l and m,
and hypotenuse as n,
\(\Large n^2 = l^2+m^2\)

you have values of l and m,
find n

Answer 8

I would assume that A would be my answer

Answer 9

why would you "assume" ?

be sure,
n^2 + 12^2+5^2 = 144 +25

n^2 =169
so, n =13

Answer 10

well I assume it because I looked like n but n was slanted plus it looked longer so I went with my common since

Answer 12

your logic would eliminate c and d, so not bad :)
