Answer: B) Adjacent interior angle
As the name implies, the angle is inside the triangle and it is adjacent (ie next to) the exterior angle. Contrast this with a remote interior angle, which is also inside the triangle, but it is not adjacent to the exterior angle in question. Alternate interior angles won't apply here because we don't have a set of parallel lines with a transversal cut.
Look at your picture
notice the coordinates for the center of the circle, the x,y or h,k values
notice how long the radius is
thus
Let the less expensive scarf be x
expensive scarf = $3 + x
According To The Question,
x+x+$3=$25
2x+$3=25
2x=22
x=$11
expensive scarf = x + $3 = $11 + $3 = $14
