Min Jee plans to add a deck off the kitchen. The deck will be 94.95 inches wide. She will use 16 boards that are each 5.7 inches wide. She has to leave a small space between the boards. If the 15 spaces between the boards are all equal, how much space will there be between each board?

1. BD is perpendicular to AC - given

2.BD bisects AC - given

3. <BDC = 90 degrees; < BDA= 90 degrees - definition of perpendicular

4. m<BDC = m<BDA - substitution property

5. m<ABD = m<CBD - definition of a bisector

6. BD = BD - reflexive property

7. ABD = CBD - Angle-side-angle congruency theorem

hope this helps at all
