If BY = 6, YC = 10, AX = 18, then XC = a: 10.8 b:5 c:30 d:48

vampirchik [111]

To answer this item, we assume that the topic is in similar polygons such that the ratio of the corresponding sides should be equal. In this item,

BY/YC = AX/XC

Substituting the known values,

6/10 = 18/XC

The value of XC from the equation is 30. The answer is letter C.
