Chapter 10 - Geometry - 10.1 Points, Lines, Planes, and Angles - Exercise Set 10.1: 30

Answer

1:126° 2:54° 3:126° 4:126° 5:54° 6:54° 7:126°

Work Step by Step

1 and 54° are Supplementary angles, Thus 1 = 180°-54°= 126° 1:126° 2 and 54° are vertical angles and thus are equal. 2: 54° 1 and 3 are vertical angles and thus are equal. 3: 126° 3 and 4 are alternate interior angles and thus are equal. 4: 126° 2 and 5 are alternate interior angles and thus are equal. 2: 54° Thus 5: 54° 5 and 6 are vertical angles and thus are equal. 6: 54° 4 and 7 are vertical angles and thus are equal. 4: 126° Thus 7: 126°
