Answer:
Segment BF = 15
Step-by-step explanation:
Segment DE is parallel to segment BC
Segment EF is parallel to segment AB.
Because segment EF is parallel to segment AB, triangles ADE and EFC are proportional. We must find the scale factor which these two triangles are proportional.
24 ÷ 20 = 1.2
Scale Factor = 1.2
18 ÷ 1.2 = 15
Segment EF is parallel to segment AB so segment EF is congruent to segment DB.
hope this helps! ps. im very sorry about the previous wrong question, but i hope this is right (,,>﹏<,,) xx
