let angle of a and b be x
then 2 × 140 + x +x = 360
280 +2x = 360
2x= 360-280
x = 80÷2
x= 40
then 2 × 140 + x +x = 360
280 +2x = 360
2x= 360-280
x = 80÷2
x= 40
Ashokkroy:
then angle a and b is 40 degree
It is llgm so the adjacent angles will be supplementry
And in llgm opp.angles are equal
sorry
then angle b will be 140 degree
so angle a will be 40 degree
Yes I had done the right
