Answer:
x = 4.
Step-by-step explanation:
2x + 3(5x - 7) = 47
2x + 15x - 21 = 47
17x - 21 = 47
17x = 68
x = 68/17
x = 4.
AD = DB
Angle ADE = Angle CDB
Angle DAE = Angle DBC (Alternate angles)
Angle DEA = Angle DCB (Alternate angles)
Since you have two congruent angles and one congruent side, triangle ADE is congruent to triangle CDB. This means that DE is congruent to DC implying D is the midpoint of CE.
