5. m∠9 = 126o; m∠10 = 54o; m∠11 = 126o
6. m∠6 = 43o; m∠7 = 137o; m∠8 = 43o

15. Vertical angles are congruent, so m∠2 = 112o.
16. 5
17. 13
18. m∠2 = 58o; m∠3 = 122o; m∠4 = 58o
19. Angles 1 and 2 form a linear pair and are supplementary. So to find m∠2, subtract m∠1 from 180o. m∠2 = 180o - 135o = 45o.
