Question

on a map, point c is 4.3km due east of point b, while point b is 2.7km on a true bearing of 143 from a. find how far east point b is from a.

Answer 1

a) Point B is 1.62 km far east from point A

b) Point C is 5.92 km south from point A

c) Point C is 2.16 km far south from point A

Explanation:

According to the following picture:

a) a=Cos(53°)×2.7 km= 1.62 km

a) b= a + 4.3 km= 5.92 km

c) c=Sin(53°)×2.7 km= 2.16 km
