Answer:
L'(4, -4)
Step-by-step explanation:
When you're given a midpoint, you can find the point equidistant on the other side of the midpoint by subtracting the relevant coordinate from <em>double that of the midpoint</em>.
Here, the line of reflection is the horizontal line y=-1, so you know only the y-coordinate will change. The reflected point will be ...
(x, y) ⇒ (x, -2-y)
so the point of interest is ...
L' = (4, -2-2) = (4, -4)
Answer:
Step-by-step explanation:
By definition, tangent lines touch a circle at one point. This one point intersects the circle at a 90 degree angle.
In any circle, the measure of an inscribed angle is exactly half of the arc it forms. Since forms an arc labelled 244 degrees, the measure of angle 2 must be
.
Angle 1 and 2 form one side of a line. Since there are 180 degrees on each side of the line, we have:
