Questions-4. In the adjacent figure if a= 40 degree ce//BA.... ..?​

Answer 1

Answer:

angle acb =85°,angle abc =55°.

Explaination:

angle ace=40°(adjacent angles are equal)

Sum of all angles at a point on a straight line is 180°,

let angle acb be x.

Therefore,180°=x+55°+40°

180°=x+95°

x=180°-95°=85°

angle abc=55°(corresponding angles are equal)
