Give the center, radius, and equation of the circle in the graph.

Answer:

$(x-2)^2+(y+3)^2=4$

Step-by-step explanation:

A circle's equation consist on the following expression: $(x-a)^2+(y-b)^2=r^2$ , where r is the magnitude of the radio, and (a,b) are the coordenates of the center of the circle.
In this case, a=2 and b= - 3, because the circle is centered in (x,y)=(2, - 3).
The radio, which is the distance between the center of the radio to any point in its border, equals r=2 (because of the scale of the graphic, in this case two squares of the grid equal 2 units, then r=2).
Finally, using the previous information to replace in the equation $(x-2)^2+(y+3)^2=4$ , where the fact that r=2 and $2^2=4$ was used.

Answer: C) angle 2 and angle 7

Imagine the parallel lines form the boundaries of river. Angles 3, 4, 5 and 6 are considered interior angles as they are in the river. Angles 1, 2, 7, 8, 9 and 10 are exterior because they're outside the river.

Angles 2 and 7 are on opposite sides of the transversal cut that I've highlighted in red (see diagram below). So that's why they're considered alternate. Combine "exterior" and "alternate" to get "alternate exterior"
