i think that should be BR not CR?

anonymous · Answer

Where did CR come from?

anonymous · Answer

sorry!  here's the correct wording for the problem: If CR = 2, RA = 3, and BC = 10, find CS

lgbasallote · Answer

where is point c???

anonymous · Answer

It's a similar triangle problem.  point C is at the bottom.  I guess you'd have to see the actual picture.  can I attach the picture on here?

lgbasallote · Answer

so CA = 10...first you need to know is AB is directly proportional to RS

try to get this:

4:10=10:x
100 = 4x
x = 25
AB = 25

anonymous · Answer

Um, okay.  I'm kind of lost.  I see how you got AB = 25, but how does CA = 10?  I thought BC = 10?

lgbasallote · Answer

CR = 4 RA = 6
CA = 10
