Find the measure of the missing angles. (someone help this is so urgent [cry])

Here,

And,

So, b + c = 180 °

77° + c = 180 ° ... { b = 77 -( vertical angle )}

subtract 77 from each sides

77 - 77 + c = 180 ° - 77 °

c = 103 °

7. d. 64

8. i. 32

9. c. 125

10. j. none of the above

11. d. 81

12. i. 216
