The answer is 160° . The parallel angles are 180° - 20° is 160° . Hope this helps. :)
It is $84.6. You multiply 1.6 by 13 which equals $20.8. Then you multiply 3.1 by 14 which equals $43.4. Then you multiply 1.2 by 17 which equals $20.4. Add them together and you get $84.6.
Hope this helps:)<span />
