Question

Two straight lines AB and CD cut each other at O. If

BOD=630

, then BOC=______​

Answer 1

1. angle bod= 63 and angle boc + angle bod = 180(linear pair).
2. angle boc+63 =180
3. angle boc=180-63=117
4. hence. angle boc= 117

Answer 2

angle bod= 63 and angle boc + angle bod = 180(linear pair).

angle boc+63 =180

angle boc=180-63=117

hence. angle boc= 117
