Examinethe trianglein the followingdiagram.Whatis the lengthof the side labeledj?You can use the law of sinesto solvethis problem.Becauseyou haveone side and the angleopposite,you
can find the constantthat appliesto the entiretriangle.This ratio will be equalto the proportionof side
and. You can use your calculatorto find the valueof the sines.
So, usingthe law of sines,the lengthof is about meters.
