Right triangle abc is reflected over ac then dilated by a scalefactor of 2/3 to form triangle dec which statement about the two triangles must be true

rectangle: 9 1/8 x 4 1/9 = 37 37/72in

parallelogram: b times h= 10.3 x 6.2 = 63.86

trapezoid: a+b/2 times h= 42.5

volume of prism: l times w times h= 36

think the answer is 30 degrees. if not than it is 20 degrees. not 100% sure. let me know if it was right.
