For this one i used the rule Sin(D)/d = Sin(A)/a which im sure is the correct method but i cant seem to get it right

Sin(95)/12 =sin(ADC) / 8

ADC =41.616 degrees

ACD = 180 -95 -41.616 =43.384 degrees

Sin(95) /12 =sin(43.384) /AD

AD =8.274 cm

Area of ACD =32.971 cm^2

Area of Parallelogram ABCD =32.971 x 2 =65.942 cm^2
