    \[\rm sin \rm \theta = \frac{ opposite }{ hypotenuse }~~~~ \cos \theta = \frac{ adjacent }{ hypotenuse } ~~\tan \theta = \frac{ opposite }{ adjacent }\]

    |dw:1433786987097:dw| to find length of side AB you should know one angle and one side so which function you should use sin ,cos or tan ??

    |dw:1433787161426:dw| you should use cos which is equal =adjacent over hyp \[\huge\rm cos 45 = \frac{ x }{ 5\sqrt{2} }\] solve for x
