Answer:
111°
Step-by-step explanation:
7 sides
sum of angles= (180×7)-360
1260-360=900
158+126+125+121+139+120+x=900
789+x=900
x=900-789
x=111°
Answer:
82<r<-164
Step-by-step explanation:
We need to form an inequality of the given statement.
82 less than r is less than -164
Less than is written as <.
82 less than r means, 82<r
r is less than -164, r<-164
Combining two statements,
82<r<-164
Hence, the expression for 82 less than r is less than -164 is 82<r<-164.
