Question

If CR = 2, RA = 3, and BC = 10, find CS.

Answer 1

any picture?

Answer 2

do you know if anything is parallel or ....

Answer 3

what you have to do in here I guess is set a proportion

Answer 4

can i assume that ba and rs are parallel??

Answer 5

and of course they are parallel

Answer 6

oops sorry.
it is given that ab is parallel to rs

Answer 7

Well if i can assume that then the proportion would be: 2 / x(SC) = 5 / 10. We know this because Triangle ABC is similar to Triangle RSC. Corresponding sides of similar triangles are in proportion. if we cross multiply we get 20 = 5x. If we divide by 5 on both sides we get x = 4. Hope this was helpful!

Answer 8

Yes!!! Thank you!
