hasan919:
u shud draw horizontal line towards the east from A. and  a vertical line towards north from T. now u hv the require triangle which is right. now use trigonometry to solve for the horizontal line, cos 35 = x/180. x = 147.4.  8)

5bi) 150 - 25 = 125
5bii) 180 - 125 = 55

5c) 180 - 125 = 55
 sin 55 = x/180
sin 55 = .81915 x180 = 147.47

hope you understand
