add angles 2 and 3 together to form 103. Then, you subtracted 103 from 180 to get 77.

Answer 7

it cant be 77 because these are the only choices
123
113

Answer 9

it must just be 103

Answer 10

let me see

Answer 11

is 103 right?

Answer 12

i believe so

Answer 13

180 -103 gives you missing angle which is 77, then inorder to get angle one you must subtract 180 to 77 get one because are supplementary which gives up 103 so angle 1 is 103

Answer 14

yes it is
