Answer :

Answer:16.40

17.40

18.100

19.100

20.140

Step-by-step To solve for the measures given in your problem, we'll analyze the information provided. We know that: - - - is a transversal of and is a transversal of We will need to use properties of angles formed by parallel lines and transversals to find the measures requested. ### Given: 1. 2. 3. ### To find: 16. Since is the angle formed at point , if lines and are parallel, the angles will be equal by the Alternate Interior Angles Theorem. Therefore, ### 17. If is a transversal and and are parallel lines, the angles and will also be equal: ### 18. Again using the properties of transversals and parallel lines: ### 19. Using the fact that the angles and are corresponding angles (since is parallel to ): ### 20. Since involves angles around point and if and are parallel, then: ### Summary of Measures: 16. 17. 18. 19. 20. If you have any further questions or need additional clarification, feel free to ask!
