Step-by-step explanation:
Angle ADE =55 degrees
Line DE is parallel to CB, and line DC acts like a transversal
=>In triangle DBC,
=>angle BDC+ angle DCB+ angle DBC =180 degrees
( Angle sum property)
=>100 + 25 + angle DBC =180 degrees
=>angle DBC= 180-125
=>angle DBC= 55 degrees
=> in triangle ADE,
angle ADE = angle DBC (corresponding angles)
=> angle ADE= 55 degrees
Answer) =>angle ADE = 55 degrees
