Answer:
r = 14.5
Step-by-step explanation:
AD is the perpendicular bisector of chord EC, so is the diameter of the circle. The radius is half the diameter.
r = AD/2 = (AB +BD)/2 = (25 +4)/2 = 29/2
r = 14.5

Segments BE and BC are 10 = √(25·4)
Answer:
3x³ + 2x² - x + 3
Step-by-step explanation:
AB = x²(3x + 2) = 3x³ + 2x²
AB - C = 3x³ + 2x² - (x - 3)
= 3x³ + 2x² - x + 3
= 3x³ + 2x² - x + 3 ← in standard form
Answer:
Step-by-step explanation:
In ΔABC, we have
The Converse of the basic proportionality theorem states that if a line divides two sides of a triangle in same ratio then the line must be parallel to the third side.
Now, it is given that , this implies that line segment DE divides AB and AC in the same ratio.
Thus, by converse of basic proportionality theorem
line segment DE= line segment BC.
Therefore, if ,then line segment DE is parallel to line segment BC .
