Exercise 17.2 1 A ship leaves harbour and sails 80 km on a bearing of 120°. It then sails 100 km on a bearing of 030º.
a Make a scale drawing of the ship's journey. Use a scale where 1 cm represents 10 km.
b How far must the ship now sail to return to the harbour?
c What bearing must the ship now sail on, to return to the harbour?

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

by the low of sine,

which is the required equation for finding the value of x,
