So far, I've got: Angle 1: 47 degrees ( because Angle 1 and the angle measuring 47° are vertical, so they are also congruent.) Angle 18: 90 degrees (because there is a right angle sign and all right angles measure 90 degrees). Can anyone answer these questions: Are angles 2 and 3 a linear pair? What are angle 1 and 3 to each other?
