Answer 2

Solution :-

given that,

• ABCD is a rectangle .
• Diagonal AC and BD intersect at 0 .
• ∠COD = 78°

so,

→ ∠COD = ∠AOB { Vertically opposite angles. }

→ ∠AOB = 78°

now, in ∆AOB we have,

→ ∠AOB = 78°

→ OA = OB { Diagonals of a rectangle bisect each other equally. => OA = OB = OC = OD . }

then,

→ ∠OAB = ∠OBA { Angle opposite to equal sides are equal in measure. }

therefore,

→ ∠AOB + ∠OAB + ∠OBA = 180° { By angle sum property. }

→ 78° + 2•∠OAB = 180°

→ 2•∠OAB = 180° - 78°

→ 2•∠OAB = 102°

→ ∠OAB = 51° (Ans.)
