Question

A and B are two cities

a) Measure the bearing of B from A

b) Measure the bearing of A from B

Answer 1

Answer:

Bearing from point A to B, can be calculated as,

β = atan2(X,Y),

where, X and Y are two quantities and can be calculated as:

X = cos θb * sin ∆L

Y = cos θa * sin θb – sin θa * cos θb * cos ∆L

put the values and calculate

Answer 2

Answer:

A = 030

B = 210

Step-by-step explanation:

A:

Draw a straight line between point A and B. Now draw 2 lines vertically up going through both points as shown in attached image. Now measure the angle between the vertical line and the diagonal line. It's 029/030.

B:

Add 180 to the 030 to get 210.

*Make sure to include the 0 before the 30 otherwise it will show up wrong*
