282
Step-by-step explanation:
C=180-112=68
A=180-68-51=61
sum of exterior angles=112+119+51=282
Answer:
60
Step-by-step explanation:
17-20=3. 60times3 equals 180. So 60
If x orignial price than 60/100*x=80/100*(x-40) and selling price =60/100*x=96
5m+48
you will need to distribute 4 to the equation in the parenthesis first
9m+4(12-m)
9m+48-4m
combine like terms
5m+48
