A. population in 1975 ........................
Answer: yes.
Step-by-step explanation:
18 people × .82 percent = 14.76
All four angles are exterior angles of the quadrilateral.
We know that the sum of exterior angles of any polygon is 360 ° .
So we can add together the four angles and solve for x:
(x+16)+(3x-1)+6x+5x = 360
15x+15=360
15x=345
x=345/15=23 °
