18. Two boats leave a duck at the same time. Each travels in a straight line but in different directions. The suggle hotesome their courses measures 38^4 One boat travels as 46 km h and the other truvels of 52.5kmh (2 marks) a) Sinch a diagram to represent the situation.

## Step 1: Diagram Representation<br />### We represent the situation with a triangle. The duck's initial position is a vertex. The two sides originating from this vertex represent the paths of the two boats. The angle between these two sides is the angle between their courses, which is $38^\circ$. We label the distance traveled by the first boat as $d_1$ and the distance traveled by the second boat as $d_2$.<br /><br />## Step 2: Distance Calculation (Boat 1)<br />### The first boat travels at 46 km/h. Let $t$ be the time in hours. The distance $d_1$ covered by the first boat is given by $d_1 = 46t$.<br /><br />## Step 3: Distance Calculation (Boat 2)<br />### The second boat travels at 52.5 km/h. The distance $d_2$ covered by the second boat is given by $d_2 = 52.5t$.
