C is congruent to S, D is congruent to T, and triangle DCA is the squiggle (I forgot what it was called) to triangle TSR. Alright, and we know this by matching up angles. See, R and A are both 74.9 degrees. Then we can see that D and T match up and C and S match up. That is how these problems get solved darling, quite simple. Hope I helped!!!!!
