Question

Please help. I don't understand how to do these problems.

Answer 1

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.
