72) m∠18 = 122°
73) m∠19 = 58°
Explanation:
Question 56 and 67 are already given for you based on the I above. Question 55 is 122° since m∠2 is 58° and you need 180° for a straight line. Assuming that Question 65 and 66 are vertical to each other, it would be the same answer for 55 and 56. Question 57 is 69° based on what is given for m∠13, same goes for Question 68. Question 58 is the same as m∠13 for its angle. Together m∠2 and m∠3 make up 127°, remaining is 53° for m∠6. If z and y are congruent then m∠5 and m∠11 should also be congruent. Because m∠6 and m∠5 are given, m∠7 should be given for you in which they should all make 180°. If line x and m are congruent then m∠18 and m∠19 should be 58° and 122° separately, ∠16 and ∠17 and vice versa. m∠5 and m∠8 should be the same. m∠7 and m∠10 should be the same and you should get the angle for m∠9.
