Answer:
Step-by-step explanation:
You have to assume that the lines that look like they are parallel really are parallel, otherwise the question cannot be answered.
If that is the case, whatever angle 1 is, angle 16 will be the same.
<1 = 100 degrees
<16 = 100 degrees.
Follow the trail. <1 and <6 are equal (Vertical Angles)
<6 = <11 (Property of parallel lines.)
<11 = <16 (Vertical angles)
<1 = <16 Equals that are equal to to other equal angles are =
