Please answer and show all work!!!

Answer 1

Answer:

14.15

Step-by-step explanation:

tan(DBA)=9/12

so angle DBA is tan^-1 (9/12) = 64 degrees

so that means that angle DBC is 90-64= 26 degrees

then we can do tan(26)=x/12

then plug in and we get around 1.17=x/12

so just miltply by 12 and get 14.15
