Consider this option:
1. if the point (4;6) is the centre of the circle and the point (2;5) is the first endpoint of its diameter, then point (4;6) is the middle point of the diameter (it means that is the middle between the 1st and the 2d endpoints of diameter).
2. using the property described above:
for x of the 2d endpoint of the diameter: x=4*2-2=6;
for y of the 2d endpoint of the diameter: y=6*2-5=7.
answer: (6;7)
The formula for the sum<span> of the interior </span>angles of a polygon<span> is equal to (n-2)*180. the </span>polygon<span> has </span>12<span>sides, so the </span>sum<span> of the interior </span>angles<span> of the </span>polygonis equal to (12<span>-2)*180 = 10*180 = 1800 degrees.</span>
Have a nice day hope this helps
