angle AOB = 132 and is also the sum of angles AOD and DOB. Hence angle AOD + angle DOB = 132° ---> 1 angle COD = 141 and is also the sum of angles COB and BOD. Hence angle COB + angle DOB = 141° ---> 2 Now we add the left sides together and the right sides of equations 1 and 2 together to form a new equation. angle AOD + angle DOB + angle COB + angle DOB = 132 + 141 ---> 3 We should also note that: angle AOD + angle DOB + angle COB = 180° Therefore substituting angle AOD + angle DOB + angle COB in equation 3 by 180 and solving for angle DOB: 180 + angle DOB = 132 + 141 angle DOB = 273 - 180 = 93°
