1. 128 (vertical angles are equal to each other)
2. 55 (the sum of the angles has to be 90 degrees because is perpendicular 55+35=90)
3. 2x+1=75
-1 -1
2x=74
2 2
X=37
(Vertical lines equal to each other that’s why I did this 2x+1=75)
5. 76 (because perpendicular and has to add 90 degrees 76+14=90)
6. 63 ( because a straight line = 180 degrees
117+63=180)
7. 21 ( because is perpendicular and has to add 90 degrees 69+21=90)
8. 49 (because is perpendicular and has to add 90 degrees 49+41=90)
9. 5x+110=180
-110 -110
5x=70
5 5
X=14
(Because straight line has to add to 180 degrees that’s why I did this 5x+110=180)
10. 53 (because straight line has to add to 180 degrees 127+53=180)
Hope that helps and you understand now :)
