Step 2: Analyse the given question. Draw a figure from the given information.

GIVEN: Angle between the bank of the river and way of the boat \angle CAB = 60\degree.

Traveled distance AC = 600 m

Determine the width of the river AB = ?

Step 2: Select the appropriate trigonometric ratio.

EXAMPLE: We need to find the width of the river(adjacent side)

\cos60\degree=\frac{AB}{AC}=\frac{AB}{600}

\frac{1}{2}=\frac{AB}{600} (Since \cos 60\degree = \frac{1}{2})

AB=\frac{600}{2})

AB = 300

The width of the river = 300 m
