Step-by-step explanation:
Since lines p || q are parallel to one another, let us find all the 8 angles,
1 and 7 are vertically opposite angles and they are equal;
since angle 1 is 75°, then angle 7 is 75°
Also, angle 7 and 5 are corresponding angles, corresponding angles are equal;
So,
angle 5 = 75°
Angle 5 is vertically opposite to angle 3,
So,
angle 3 = 75°
To find angle 4,
angle 4 and angle 5 are angles on a straight line;
sum of angles on a straight line = 180°
angle 4 + angle 5 = 180°
angle 4 = 180 - 75 = 105°
Angle 2 and Angle 4 are corresponding angles and they are equal;
So angle 2 = 105°
Angle 4 and angle 6 are vertically opposite and they are equal;
angle 6 = 105°
Angle 6 and 8 are corresponding angles, they are equal;
angle 8 = 105°
