Question

In the figure angle EBC = 115 degree and Angle DAB = 100 degree. Find angle ACB.PLEASE HELP!!!!

Answer 1

Step-by-step explanation:

DAB+BAC equal to 180 degree in the figure angle EBC equal to 115degree and angle DAB equal to 100 degree

Answer 2

Answer:

angle ACB = 35°

Step-by-step explanation:

EBC + ABC = 180° ( linear pair)

115° + ABC = 180°

ABC = 180°- 115°

Therefore angle ABC = 65°

Also, BAD + BAC = 180° ( linear pair)

100° + BAC = 180°

ABC = 180°- 100°

Therefore angle ABC = 80°

Now, In ∆ ABC ,

ABC + BAC + ACB = 180° ( Angle sum property of a triangle )

That is , 65° + 80 ° + ACB = 180 °

ACB + 145° = 180°

So,. ACB = 180° - 145°

Therefore , Angle ACB = 35°
