In the figure shown, t || x and k || w and m∠3 = 20°. Choose the list which includes all of the other angles that measure 20°. There are two horizontal parallel lines k and w are cut by transversal parallel lines x and t. The top left angle is denoted by 1 when transversal line t makes an angle with horizontal line k. The supplementary angle of angle 1 (which is top right angle) is denoted by 2 and opposite angle is denoted by 3. The opposite angle of 2 is denoted by 4. The corresponding angle of 1 which is formed by crossing the line w and t is denoted by 5 and the corresponding angle of 2 is denoted by 6. The opposite angle of 5 is denoted by 7 and opposite angle of 6 is denoted by 8. Similarly, When line k and line x are crosses the top left angle is denoted by 16 which is also corresponding angle of 1. The corresponding angle of 2 is denoted by 15. The opposite angle of 16 is denoted by 14 and opposite angle of 15 denoted by 13. The corresponding angle of 16 which is formed by crossing the line w and x is denoted by 11 which is also corresponding angle of 5. The corresponding angle of 15 is denoted by 10 which is also corresponding angle of 6. The opposite angle of 11 is 9 and opposite angle of 10 is 12.

A. 1
B. 1, 5, 7
C. 1, 14, 16
D. 1, 5, 7, 9, 11, 14, 16
