i know what ratio is but in this problem what ratio using the angles or sides??

anonymous · Answer

Just plug in 7 for x. You see, x√2 --> 7√2. Just idivde by √2 in order to get both a and b.

anonymous · Answer

they are not the same length correct

anonymous · Answer

a and b are the same length. c is different though.

anonymous · Answer

alright i got 7 then for a and b

anonymous · Answer

Yup

anonymous · Answer

If you have a or b and need to get c, just stick a √2 next to it. If you need to get a or b, just take away the √2. If there is no √2, divide by √2.
