Answer: 12.5
Triangle Proportionality Theorem: If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally. The converse is also true.
For this one we use the Angle bisector theorem: In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
Steps:
DC/BD = AC/AB
x/14 = 25/28
x = 25/28 * 14
x = 12.5
Now that you know how to do it, hope that you can do more sums like this in the future! And brainliest pwease if that's the answer your looking for!
