Answer:
A) a straight line or segment that touches a curve at a point 90 degrees to the radius of the circle it touches.
D) a straight line or segment that touches a curve and matches the curve's slope at that point
Step-by-step explanation:
- tan(x) = opposite/adjacent
- A tangent is a straight line that touches the edge of a curve or circle at one point, but does not cross it.
- The slope of a curve at a point is equal to the slope of the straight line that is tangent to the curve at that point.
