Answer:
ODC = 90°
Step-by-step explanation:
Let assume that AC is also a line .
So this is pentagon . The sum of all angles of pentagon is 540 degree .
AB||CD [OD is perpendicular to CD }
AB||CD {CA is perpendicular to CD }
AB||CD {AC is perpendicular to AB }
So , We got all the angles . Which are
∠ACB + ∠BAC + ∠CDO +∠DOB + ∠OBA
90° + 90° + 90° + 152° + 118°
540°
