The diagonals of a rectangle ABCD meet at O. If angle BOC is equal to 44 degree, find angle OAD.

• geometry -

180-44=136 degrees

• clad's answer is incorrect - geometry -

The diagonals of a rectangle produce pairs of isosceles triangle.
So triangle BOC is isosceles, and each of the base angles must be 68°
(68+68+44=180)
since angles BCO and OAD are alternate angles for parallel lines,
angle OAD = 68°
