Hey.

Would anyone be kind enough to help me answer the four questions attached?

Thanks so much!

1) angle ACD=48 alt angles
angle CAD=48 (base angles = issos triangle)(since AD=DC)
therefore angle ADC=84( angle sum triangle)
2) AE/BE=DE/EC=3/4
angle AED=angle BEC (VERT opp)
therefore simillar 2 sides in ration and common angle
