Answer:
1=55°
2=125°
4=125°
5=125°
6=55°
7=125°
8=55°
Step-by-step explanation:
7= 125° because a line is 180°, so 55° + angle 7 = 180°, using simple algebra we can subtract 55 from both sides getting angle 7 = 125°
8= 55° because vertical angles are always congruent
4= 125° because all vertical angles are congruent
6= 55° because alternate interior angles are always congruent so angle 6 = 55°
1= 55° because vertical angles are always congruent
2=125° because alternate interior angles are always congruent so angle 2 = angle 7
5=125° because vertical angles are always congruent
