Question

Write the measurements for the angles.

Answer 1

Answer:

1: 45

2: 135

3: 45

4: 135

5: 60

6: 120

7: 60

8: 120

9: 75

10: 105

11: 75

12: 105

Step-by-step explanation:

1, 2, 3, and 4 and 9, 10, 11, and 12 can be solved using the vertical angle and supplementary angle rules. Vertical angles are always the same and supplementary angles always add up to 180. But to find 5, 6, 7, and 8, you need to find 5 using the rule where all the angles in a triangle add up to 180. Since we know the angles for 9 and 3, we can find the angle 5 and then we can finish finding the rest of the angles.

I hope this helps!
