Answer:
-2.1
Step-by-step explanation:
-7.3 - 11.2 - 1.7 + 0 + 0 +2.2 + 3.3
--------------------------------------------------
7
= -2.1
157 degrees ... set 4x-5 = x+16 then solve, you should get x=7, plug in 7 for one of the equations and you'll get 23. subtract 23 from 180 and get 157. hope that helped :)
