Answer:
60°
Step-by-step explanation:
ABCO is a parallelogram (opposite sides are parallel).
AO is equal to the radius of the circle, so BC must also equal the radius.
CO is equal to the radius of the circle, so AB must also equal the radius.
If we draw a line from O to B, we split the parallelogram into two triangles. Since OB is equal to the radius of the circle, each triangle is an equilateral triangle. Therefore, angle A is 60°.

Answer:
(-3,-4)
Step-by-step explanation:
You draw it...
So since we are reflecting across the x-axis, we want the x-coordinate to stay the same. We just need to take the opposite of y.
