OpenStudy (anonymous):

.k

find cd by using 6^2=3.29^2+cd^2

OpenStudy (anonymous):

then use tan60=cd/bd

OpenStudy (anonymous):

so my answer is 2 sqrt 3

OpenStudy (anonymous):

i have no calculator

OpenStudy (anonymous):

6*cos30 =5.196

OpenStudy (anonymous):

cd=9

OpenStudy (anonymous):

your answer is 5.196

OpenStudy (anonymous):

wrong

OpenStudy (anonymous):

no answer choices are that

OpenStudy (anonymous):

sorry the answer is \[\sqrt{3}\]

OpenStudy (anonymous):

ad=5.196 sin60=6/ab bd=ab-ad bd=6.928-5.196
