The plane has searched 12,950 hectares. the ratio between hectares to square miles is: 1 hectare is 2.471 acres
D. the angles are alternate which means that they will add up to 180 so the answer is D
hope this helps :)
Try this solution:
Common view of the equation of the circle is (x-a)²+(y-b)²=r², where point (a;b) is centre of the circle, r - radius.
1. using the coordinates of the centre and point (2;13) it is possible to define the radius of the circle: r=√(5²+12²)=13;
the equation is (x+3)²+(y-1)²=13² or (x+3)²+(y-1)²=169;
2. using the coordinates of the centre and the radius: (x-2)²+(y-4)²=6² or (x-2)²+(y-4)²=36.

Answer:
100°
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary:
x° +80° = 180°
x° = 100° . . . . . . . subtract 80°
