Question

The diagonals AD and BD intersect at O in a rectangle ABCD.If angle AOD=45 degree,then angle DAC is

Answer 1

Answer:67.5 degress

Step-by-step explanation:since abcd is a rectangle diagonals will intersect at centre.

taking, diagonals AC and BD and centre O , they form a isoscelus triangle AOD.

Now by angle sum method we get

angle AOD +2X =180    (X=∠OAD=∠ODA,THE TRIANGLE IS ISOSCELUS)

solving the equation we get ∠DAC=X=67.5

hope this clears your doubt
