Question

In a rectangle ABCD angle aob 80 degree find angle ADO and angle DCA ​

Answer 1

Answer:

I am very bad at maths but very good at other

Answer 2

Step-by-step explanation:

let angle ADO = 1

angle DCA = 2

angle AOB = angle DOC (vertically opposite angle)

angle AOB + angle AOC = 180 ( linear pair)

80 + AOC = 180

AOC = 180 - 80

AOC = 100

angle AOC =angle BOC (vertically opposite angle)

angle

after this prove by alternate interior angles
