Question

The diagonals of a rectangle ABCD intersect at point 'O'. If ∠AOB = 78°,then ∠AOD is:

Answer 1

Answer:

The value of angleye AOD is 102

Step-by-step explanation:

In ABCD,

angle AOB=78(given)

So ,angleAOD=180-78 (Linear Pair).

=102.

Answer 2

Answer:

angle AOD = 102°

Step-by-step explanation:

angle AOD + angle AOB = 180°( angles in linear pair)

•

• • angle AOD + 78° = 180°

so , angle AOD = 180° - 78°

hence ,angle AOD = 102°
