4​

Answer 1

Answer:

ABCD is a rectangle. We know that the diagonals of the rectangle are equal and bisect each other.

⟹BD=AC and AO=BO=OC=OD

In △ABO,

∠OAB=∠OBA=50∘ ---Angles opposite to the equal sides in a triangle are equal.

In △AOB,

∠AOB+∠OAB+∠OBA=180∘ ---sum of interior angles of a triangle

∴∠AOB=x=180∘−50∘−50∘=80
