we know the mid point formula
(x ,y)=<u>x</u><u>1</u><u>+</u><u>x</u><u>2</u> , <u>y</u><u>1</u><u>+</u><u>y</u><u>2</u>
2 2
=<u>0</u><u>+</u><u>1</u><u>0</u> , <u>6</u><u>+</u><u>0</u>
2 2
=(5,3)
centre of circle(x, y)=(5,3)
Only 2 or more 180 degree angles can be considered parallel.
6/10 + 7/12 = 142/120 = 71/60 = 1.18 (One whole number, and 11/60)
