Please help :) A B&C form the vertices of a triangle.
CAB = 90°, ABC = 70° and
AC = 9.5.
Calculate the length of AB rounded to 3 SF.

And please explain how :)
Thanks

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+=+%2836%2fx%29%5e2+

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

++x%5e2+=+1296%2f2+=+648+
