HW AC Chapters 3 Microsoft Edge nmentProblemiD-89379762 HW AC Chapters Item 10 artA Which direction should you go to reach the treasure? The treasure map in the figure gives the following directions to the buried treasure "Start at the old oak tree, walk due north for 540 paces, then due east for 120 paces Dig But when you arrive, you find an angry dragon just north of the bee. To avoid the dragon, you set off along the yellow brick road at an angle 60 east of north Ather walking 310 paces you see an opening through the woods (Figure 1) 67.7 west of north X Incorrect; Try Again; 3 attempts remaining Figure 1 of 1 Part B × Treaure How far should you go to reach the treasure? Yellow hrick road paces °Type here toExplanation / Answer
A )
the destination location = 540 i + 120 j
final pposition = 310 ( sin60 i + cos60 j )
the desired path = (540 i + 120 j) - ( 310 ( sin60 i + cos60 j ) )
the desired path = (540 i + 120 j) - ( 310( 0.866 i + 0.5 j ) )
= 271.54 i - 35 j
direction = tan-1 ( 35/271.54 ) = - 7.34o west of north
B )
S = ( 271.542 + 352 )1/2
S = 273.78 paces
