its 180 becoz c and d are vertically opp angles and b and c form linear pair so by solving it we get 180
thanks

b = 180 - c
d = c ( vertically opposite angles)
Therefore,
b + 2c - d
= 180 - c + 2c - c
= 180 - 2c + 2c
= 180
d = c ( vertically opposite angles)
Therefore,
b + 2c - d
= 180 - c + 2c - c
= 180 - 2c + 2c
= 180
therefore (4)
so we can take any of the one angle as vertically opp and one linear pair
then only the equation will be solved
No there might be other methods.
hm...
okk
but this is the one way to solve
Right!
