Question

Please solve this for me the best one will be marked as brainlist ​

Answer 1

Answer:

As BCD is a straight line it is 180.

so ACD+ACB=180

56+ACB=180

ACB=180-56

ACB=124

According to Angle sum property of a triangle,

add all angles of triangle ABC

40+124+ABC=180

164+ABC=180

ABC=180-164

ABC=16

Answer 2

Answer:

Step-by-step explanation:

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)
