1.	two radar stations A and B are 80km apart and B is due east of A.One aircraft is on a bearing 030 from A and 346 fromB. A second aircraft is on a bearing of 325 from A and 293 from B.How far apart are the two aircraft?
Answer» Given: please find the question. To find: distance=? Solution: POINT: $A(0,0) \ \ \ \ \ B(80, 0)$ Claculating Slop of AC, $\tan 60^{\circ} = \sqrt{3} = 1.732$ Claculating Slop of BC, $\tan 104^{\circ} = - 4.011$ Claculating Slop of AD, $\tan 125^{\circ} = - 1.428$ Claculating Slop of BD, $\tan 157^{\circ} = - 0.424$ When point C intersepts: $\to y= 1.732 x......(a)\\\to y= -4.011(x - 80)......(b)\\$ solve EQUARTION (a) and (b): $\to x_1 = 55.873 \\\to y_1 = 96.772$ When point D intersepts: $\to y= -1.428 x......(c)\\\to y= 0.424(x - 80)......(d)\\$ solve equartion (c) and (d): $\to x_1 = 18.315 \\ \to y_1 = -26.154$ Calculating diatance: $\bold{D= \sqrt{(y_2-y_1)^2 +(x_2-x_1)^2}}$ by putting the value the distance is "128.535" .
