= 180°
and 
Therefore, 
= 180°
32° + + 58° = 180°
= 180° - 90°
= 90°
12. Since, 
= 32°
=

Answer:
x=6, y=2
Step-by-step explanation:
Points 
on the circle satisfy 
.
Points inside the circle satisfy 
.
Points outside the circle satisfy 
.
We have
so the point (2, 8) lies inside the circle.
$46 divided by 5 which equals $9.50
Rent during the 8th year is $3072
