Question

math question..

Answer 1

From the similar triangles in the diagram, write a proportion using the ratio BC/DC

Answer 2

BC and DC are both in triangle DCB.
BC is the longest rectangular side (or how that is called, hope you know what I mean)
DC is the hypothenuse.

If you take those sides in another triangle (all visible triangles are similar), they will have the same ratio.

Answer 3

multiple choice
BC/DC=AB/AD
BC/DC=AD/AB
BC/DC=BD/AD
BC/DC=AD/BD

Answer 4

the first one?

Answer 5

True!

Answer 6

That's all there is to it!

Answer 7

it was acually the third one but thankyou though.

Answer 8

I made a mistake: BC is the shortest side.
BC/DC=AC/BC=AB/BD.
I don't see the right answer in the options...
