If point c is between points a and b, then + cb = ab. a. abc b. ab c. ca d. bc

Here we are given that C is between A and B.

So using the midpoint rule, sum of whole length AB will be addition of lengths AC and BC

so we can say that option C. CA is the correct choice as it satisfies the given condition.

Points A and B are the end points and C is somewhere between them.

In order to find the total length of AB, you would add CA and CB together.

The answer would be C. CA

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+
