Question

In the given figure, AB || CD and O is the centre of the circle. If angle ADC = 25, then the
measure of angle AEB is
AB​

Answer 1

Answer:

measure of AEB is 40.by joining OA and OB

Answer 2

Step-by-step explanation:

Join AC , BD & BC

•

• • <CAD = <CBD =90°

( Angle in a semicircle is a right angle)

also, AB||CD

•

• • <BAD = <ADC =25° ( Alternate interior angles are equal )

hence < AEB = 40° Proved
