Answer:
m<1 =163 degrees
163,17,163,17 (all in degrees)
163,17,163,17 (all in degrees)
Explanation:
I have duplicated and joined a chart (in figure 1) of the issue.
For simplicity of comprehension, I have connected a second outline which is named.
On line a
17+<CBE=180 (Linear Pair Postulate)
m<2=<CBE=180-17=163 degrees
<ABG=<CBE=163 degrees (Vertically Opposite Angles)
<ABE=<GBC= 17 degrees(Vertically Opposite Angles)
On line b
m<1=<DEB=<ABG=163 degrees (Corresponding Angles)
<BEF=<GBC= 17 degrees (Corresponding Angles)
<HEF=<DEB=163 degrees (Vertically Opposite Angles)
<DEH=<BEF=17 degrees (Vertically Opposite Angles)
Accordingly:
m<1 =163 degrees
Clockwise from upper left, the points shaped with line an are: 163 degrees, 17 degrees, m<2=163 degrees and 17 degrees.
Clockwise from upper left, the points shaped with line b are: m<1=163 degrees, 17 degrees, 163 degrees, and 17 degrees.
