Answer:
ship sails 35 km on a bearing of 042 degrees
A right triangle is formed with sides, north/south (a) and the east west (b)
sin%2842%29+=+b%2F35
b = 23.42
cos%2842%29+=+a%2F35
a = 26.01
Verified answer
Step-by-step explanation:
1) cos42= AB/35
AB=35cos42
.: AB = 26.0KM
2) Sin42= OB/35
OB=35sin42
.: OB=23.4 km
