Sagot :

Answer:

1. 100°

2. angle 7 and angle 6

3. 20°

4. angle 1 and angle 12

5. 180°

Solution:

1. angle 12 = angle 1 = 100°

2. angle 7 and angle 6;

3. angle 8 = angle 2 = 20°

angle 2 + angle 12 = 180°

=) angle 12 = 180° – 20° = 160°

4. angle 1 and angle 12;

5. m//h

angle 9 + angle 7 = 180°

Answer:

1.  106°

2. ∠12 and ∠5

3. 160°

4. ∠3 and ∠6

5. they are supplementary

Step-by-step explanation:

1. they are vertical angles so they are equal

2. just look at them

3. since angles 8 and 7 are alternate interior angles, they must be equal, so ∠12 = 180 - 20 = 160

4. just look at them

5. ∠7 = ∠8, since they are alternate interior angles so if they would be interchanged, ∠9+∠7 = 180
