Answer:
0.81
Step-by-step explanation:
1. statement: angles 1 and 2 are supplementary, reason: adjacent angles on a straight line are supplementary
2. reason: Vertical angles are congruent
3. reason: Parallel lines for supplementary interior angles on the same side as the transverse
4. statement:angles 1 and 5 are equal reason:If two angles are supplementary to the same angle, they are congruent
A because it start at 20 and divided 1/2 each time. And when you solved 2/ 1/2 , you get 4 and that is correct because you have 4 arrows.
Answer:
I think it would be 5 and 5 of each solution
