Question

please give me answer fast plz.​

Answer 1

Answer:

1. 180-40 =140

2. 90-47 =43

3. 110 (opposite angles

4. 180-60 =120

Answer 2

Answer:

Your answers are right

And the reasons are

1.The sum of a linear pair should be 180 so 140 is the right answer

2.The Sum of the angles should be 90 as the overall angle is a right angle.

So 43 is the right answer.

3.Intersecting lines add up to a complete angle that is 360 degree. And another property is that if an angle (that is 110 in your case)will be the same in the opposite side.

4.Same thing as said before in the 3rd question so since one angle is 60 its opposite will be the same that is 60 and its opposite side will be 180-60 = 120.

Thank you

Hope this answer helps you
