short answer no they are not congruent. the scale factor would be 1 if they were. jl and rt should both be the same length (they are opposite angles marked with 2 quarter circles). they are not equal. so the scale factor is not 1.
to get from jkl to rst you must multiply every length of jkl by = 20 / 25 or 4/5. so 15 * 4/5 = 12 which works. 4/5 * 20 = 16 which also works.
the two triangles are similar.
the answer is b. m∠ pos + m∠ por = 180
because if you already know that m∠poq equals 90 because it is a right angle
then all you have to do is take 90 from 180 which is 90 then divide 90 by two which is 45
now you have the measurement for the two acute angles 45
which makes m∠pos = 45 and m∠qor =45
now you have to add 90 and 45 and 45 all together then you will have 180
