is there a series of rigid transformations that could map
arst to axyt? if so, which transformations could be
used?

no, arst and axyt are congruent but arst cannot
be mapped to axyt using a series rigid transformations.
no, arst and axyt are not congruent.
yes, arst can be reflected across the line containing
rt and then rotated about t so that s is mapped to y
yes arst can be translated so that s is mapped to y
and then rotated about s so that ris mapped to x

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

$655.61 which is option c

step-by-step explanation:

price of house =   $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

                                        =

                                        =$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

                                      =$35770

remaining money = $146000-35770

                                =$110230

new mortgaged payment = 5 % of 110230

                                            =  

                                            =$655.61
