Answer:
11a. m <1 = 131 12a. m <1 = 42
11b. m <2 = 49 12b. m <3 = 75
11c. m <3 = 131 12c. m <4 = 42
11d. m <4 = 49 12d. m <5 = 63
11e. m <5 = 131 12e. m <6 = 75
11f. m <6 = 49 12f. m <7 = 105
11g. m <8 = 49 12g. m <8 = 75
11h. m <9 = 92 12h. m <10 = 75
11i. m <10 = 88 12i. m <11 = 42
11j. m <11 = 92 12j. m <12 = 138
11k. m <12 = 88 12k. m <13 = 42
11l. m <13 = 92 12l. m <14 = 138
11m. m <14 = 88
11n. m <15 = 92
Step-by-step explanation:
When lines are parallel to each other than:
Corresponding Angles are equal.
Alternate Interior Angles are equal.
Alternate Exterior Angles are equal.
Consecutive Interior Angles add up to 180 degrees.
You can check some math websites for definitions of these angle relationships.
