I'll get you started . . .
An aircraft flies 400km from a point on a bearing of 25° to
and then 700km on a bearing of 80° to arrive at .
a) How far north of is ?
b) How far east of is ?
c) Find the distance and bearing of from ?Code:P Q o B : : * | : : * | : : * | : : 80° * | : A: * 10° | : o - - - - - - - - + C : *| | :25°* | | : * | | : * | | :*65° | | o - - + - - - - - - - - * O D E
The plane starts at on a bearing of 25°: .
. . The distance is 400 km: .
Then it is on a bearing of 80°: .
. . The distance is 700 km: .
(a) We want the distance
In right triangle ADO: .
. . Since
In right triangle BCA: .
Therefore: . km.
