Please help , I’m having a hard time .

Answer:
1. In between F and A = 50
2. In between A and C = 20
3. In between B and G = 50
4. In between C, E, and G = 130
Step-by-step explanation:
1. Because for it to equal to 180 add 130 and 20 to get 150. Subtract 180 and 130 to get 50.
2. In between D and B and in between A and C they are vertical of one another. They would equal the same.
3. Same as above but with A and F, B and G
4. Same as above but with their variables.
