Answer
1:68°
2:68°
3: 112 °
4:112°
5:68°
6:68°
7:112°
Work Step by Step
1 and 112° are Supplementary angles,
Thus 1 = 180°-112°= 68°
1:68°
1 and 2 are vertical angles (Opposite angles formed when the two lines intersect) and thus are equal.
2: 68°
112° and 3 are vertical angles and thus are equal.
3: 112°
3 and 4 are alternate interior angles and thus are equal.
4: 112°
2 and 5 are alternate interior angles and thus are equal.
2: 68°
Thus 5: 68°
5 and 6 are vertical angles and thus are equal.
6: 68°
4 and 7 are vertical angles and thus are equal.
4: 112°
Thus 7: 112°
