Question

find the value of x and y.​

Answer 1

Answer:

x=50 and y=40

Step-by-step explanation:

angle ADO= angle DAO

as in rectangle diagonals are equal and diagonals bisect each other

therefore triangle ADO is isoceles

Angle AOD=180- angle DOC = 180-100=80

Hence 2 X angle ADO=80

angle ADO=40

similarly, angle ABO= angle BAO

angle DAO + angle BAO= 90 (rectangle)

angle BAO= 90-40=50

angle ABO= 50
